Please have a look at "How to contribute?".
First, the jQuery library needs to be included. Then Twitter Bootstrap - both the Javascript library and the CSS stylesheet - needs to be included.
<!-- Include Twitter Bootstrap and jQuery: --> <link rel="stylesheet" href="css/bootstrap.min.css" type="text/css"/> <script type="text/javascript" src="js/jquery.min.js"></script> <script type="text/javascript" src="js/bootstrap.min.js"></script> <!-- Include the plugin's CSS and JS: --> <script type="text/javascript" src="js/bootstrap-multiselect.js"></script> <link rel="stylesheet" href="css/bootstrap-multiselect.css" type="text/css"/>
The jQuery library can also be included using a CDN, for example the Google CDN:
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
Note that the plugin will work both with version 2.x of the jQuery library as well as with version 1.10.x of the jQuery library. So for using the Google CDN you may have to adjust the version.
Now simply use HTML to create your select input which you want to turn into a multiselect. Remember to set the multiple attribute as to get a real multiselect - but do not worry, the plugin can also be used as usual select without the multiple attribute being present.
<!-- Build your select: -->
<select id="example-getting-started" multiple="multiple">
<option value="cheese">Cheese</option>
<option value="tomatoes">Tomatoes</option>
<option value="mozarella">Mozzarella</option>
<option value="mushrooms">Mushrooms</option>
<option value="pepperoni">Pepperoni</option>
<option value="onions">Onions</option>
</select>
In the end, simply call the plugin on your select. You may also specify further options, see the Options tab for further information.
<!-- Initialize the plugin: -->
<script type="text/javascript">
$(document).ready(function() {
$('#example-getting-started').multiselect();
});
</script>
Use Firebug, Chrome Developer Tools to get the best out of the below examples.

XSS injection is a serious thread for all modern web applications. Setting
<script type="text/javascript">
$(document).ready(function() {
$('#example-xss').multiselect();
});
</script>
<select id="example-xss" multiple="multiple">
<option value="1"><script>alert(1);</script></option>
</select>
On the other hand, when setting
<script type="text/javascript">
$(document).ready(function() {
$('#example-xss-html').multiselect();
});
</script>
<select id="example-xss-html" multiple="multiple">
<option value="1">>span style="color:red"<Option 1>/span></option>

If set to
When using
<script type="text/javascript">
$(document).ready(function() {
$('#example-enableClickableOptGroups').multiselect({
enableClickableOptGroups: true
});
});
</script>
Note that this option does also work with disabled options:
<script type="text/javascript">
$(document).ready(function() {
$('#example-enableClickableOptGroups-disabled').multiselect({
enableClickableOptGroups: true
});
});
</script>
Note that the behavior of
<script type="text/javascript">
$(document).ready(function() {
$('#example-enableClickableOptGroups-onChange').multiselect({

<script type="text/javascript">
$(document).ready(function() {
$('#example-enableCollapsibleOptGroups-enableClickableOptGroups').multiselect({
enableClickableOptGroups: true,
enableCollapsibleOptGroups: true
});
});
</script>

$(document).ready(function() {
$('#example-enableCollapsibleOptGroups-collapsed').multiselect({
enableCollapsibleOptGroups: true,
buttonContainer: '<div id="example-enableCollapsibleOptGroups-collapsed-container" />'
});
$('#example-enableCollapsibleOptGroups-collapsed-container .caret-container').click();
});
</script>
Combining the above with
Again, note, that the behavior of combining
<script type="text/javascript">
$(document).ready(function() {
$('#example-enableCollapsibleOptGroups-enableClickableOptGroups-enableFiltering-includeSelectAllOption').multiselect({
enableClickableOptGroups: true,
enableCollapsibleOptGroups: true,

However, note that messing with the template's classes may cause unexpected behavior. For example the button should always have the class .multiselect,
In addition, note that other options may also have influence on the templates, for example the buttonClass option.
<script type="text/javascript">
$(document).ready(function() {
$('#example').multiselect({
templates: {
button: '<button type="button" class="multiselect dropdown-toggle" data-toggle="dropdown"></button>',
ul: '<ul class="multiselect-container dropdown-menu"></ul>',
filter: '<li class="multiselect-item filter"><div class="input-group"><span class="input-group-addon"><i class="glyphicon glyphicon-search"></i></span><input class="form-control multiselect-search" type="text"></div></li>',
filterClearBtn: '<span class="input-group-btn"><button class="btn btn-default multiselect-clear-filter" type="button"><i class="glyphicon glyphicon-remove-circle"></i></button></span>',
li: '<li><a href="javascript:void(0);"><label></label></a></li>',
divider: '<li class="multiselect-item divider"></li>',
liGroup: '<li class="multiselect-item group"><label class="multiselect-group"></label></li>'
}
});
});
</script>
For example other elements instead of buttons may be used by adapting the template:
<script type="text/javascript">
$(document).ready(function() {
$('#example-filter-placeholder').multiselect({
buttonContainer: '<div></div>',
buttonContainer: '',
buttonClass: '',
templates: {
button: '<span class="multiselect dropdown-toggle" data-toggle="dropdown">Click me!</span>'
}
});
});
</script>
<style type="text/css">
span.multiselect {
padding: 2px 6px;
font-weight: bold;
cursor: pointer;
}
</style>
The style of the plugin is fully adaptable through CSS; a completely rendered example is shown below - including select all option, filter and option gorups_
<ul class="multiselect-container dropdown-menu">
<!-- Filter -->
<li class="multiselect-item multiselect-filter" value="0">
<div class="input-group">
<span class="input-group-addon"><i class="glyphicon glyphicon-search"></i></span>
<input class="form-control multiselect-search" type="text" placeholder="Search">
<span class="input-group-btn">
<button class="btn btn-default multiselect-clear-filter" type="button"><i class="glyphicon glyphicon-remove-circle"></i></button>
</span>
</div>
</li>
<!-- Select all -->
<li class="multiselect-item multiselect-all" style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: rgb(234, 234, 234); background: rgb(243, 243, 243);">
<a tabindex="0" class="multiselect-all"><label class="checkbox" style="padding: 3px 20px 3px 35px;"><input type="checkbox" value="multiselect-all"> Select all</label></a>
</li>
<!-- Collapsible and clickable opt group -->
<li class="multiselect-item multiselect-group">
<a href="javascript:void(0);">
<label><input type="checkbox" value="undefined"><b> Group 1</b></label>
<span class="caret-container"><b class="caret"></b></span>
</a>
</li>
<!-- Disabled and hidden option (hidden because of collapsible opt groups) -->
<li class="disabled hidden">
<a tabindex="-1"><label class="checkbox"><input type="checkbox" value="1-1" disabled=""> Option 1.1</label></a>
</li>
<!-- Hidden but select option -->
<li class="active hidden">
<a tabindex="0"><label class="checkbox"><input type="checkbox" value="1-2"> Option 1.2</label></a>
</li>
<!-- ... -->
<!-- Another opt group -->
<li class="multiselect-item multiselect-group">
<a href="javascript:void(0);">
<label><input type="checkbox" value="undefined"><b> Group 2</b></label>
<span class="caret-container"><b class="caret"></b></span>
</a>
</li>
<!-- Visible but not selected option -->
<li>
<a tabindex="0"><label class="checkbox"><input type="checkbox" value="2-1"> Option 2.1</label></a>
</li>
</ul>
The most important classes are: multiselect-container, multiselect-filter, multiselect-all, multiselect-item, multiselect-group as well as disabled and active. Both for collapsing and filtering options, the classes multiselect-filter-hidden and multiselect-collapsible-hidden are used.
.multiselect('destroy')
|
This method is used to destroy the plugin on the given element - meaning unbinding the plugin.
<script type="text/javascript">
$(document).ready(function() {
$('#example-destroy').multiselect();
$('#example-destroy-button').on('click', function() {
$('#example-destroy').multiselect('destroy');
});
});
</script>
|
.multiselect('refresh')
|
This method is used to refresh the checked checkboxes based on the currently selected options within the
<script type="text/javascript">
$(document).ready(function() {
$('#example-refresh').multiselect();
$('#example-refresh-select').on('click', function() {
$('option[value="1"]', $('#example-refresh')).prop('selected', true);
$('option[value="3"]', $('#example-refresh')).prop('selected', true);
$('option[value="4"]', $('#example-refresh')).prop('selected', true);
alert('Option 1, 2 and 4.');
});
$('#example-refresh-deselect').on('click', function() {
$('option', $('#example-refresh')).each(function(element) {
$(this).removeAttr('selected').prop('selected', false);
});
});
$('#example-refresh-button').on('click', function() {
$('#example-refresh').multiselect('refresh');
});
});
</script>
|
.multiselect('rebuild')
|
Rebuilds the whole dropdown menu. All selected options will remain selected (if still existent!).
<script type="text/javascript">
$(document).ready(function() {
$('#example-rebuild').multiselect();
$('#example-rebuild-button').on('click', function() {
$('#example-rebuild').multiselect('rebuild');
});
$('#example-rebuild-add').on('click', function() {
$('#example-rebuild').append('<option value="add1">Addition 1</option>
<option value="add2">Addition 2</option><option value="add3">Addition 3</option>');
});
$('#example-rebuild-delete').on('click', function() {
$('option[value="add1"]', $('#example-rebuild')).remove();
$('option[value="add2"]', $('#example-rebuild')).remove();
$('option[value="add3"]', $('#example-rebuild')).remove();
});
});
</script>
|
.multiselect('select', value)
|
Selects an option by its value. Works also using an array of values.
<script type="text/javascript">
$(document).ready(function() {
$('#example-select').multiselect();
$('#example-select-button').on('click', function() {
$('#example-select').multiselect('select', ['1', '2', '4']);
alert('Selected 1, 2 and 4.');
});
});
</script>
The method provides an additional parameter:
<script type="text/javascript">
$(document).ready(function() {
$('#example-select-onChange').multiselect({
onChange: function(option, checked, select) {
alert('onChange triggered ...');
}
});
$('#example-select-onChange-button').on('click', function() {
$('#example-select-onChange').multiselect('select', '1', true);
});
});
</script>
The above parameter does also work when selecting multipe values. Note that
<script type="text/javascript">
$(document).ready(function() {
$('#example-select-onChange-array').multiselect({
onChange: function(option, checked, select) {
alert('onChange triggered ...');
}
});
$('#example-select-onChange-array-button').on('click', function() {
$('#example-select-onChange-array').multiselect('select', ['1', '3'], true);
});
});
</script>
|
.multiselect('deselect', value)
|
Deselect an option by its value. Works also using an array of values.
<script type="text/javascript">
$(document).ready(function() {
$('#example-deselect').multiselect();
$('#example-deselect-button').on('click', function() {
$('#example-deselect').multiselect('deselect', ['1', '2', '4']);
alert('Deselected 1, 2 and 4.');
});
});
</script>
The method provides an additional parameter:
<script type="text/javascript">
$(document).ready(function() {
$('#example-deselect-onChange').multiselect({

alert('onChange triggered ...');
}
});
$('#example-deselect-onChange-button').on('click', function() {
$('#example-deselect-onChange').multiselect('deselect', '1', true);
});
});
</script>
The above parameter does also work when deselecting multiple options. Note that
<script type="text/javascript">
$(document).ready(function() {
$('#example-deselect-onChange-array').multiselect({
onChange: function(option, checked, select) {
alert('onChange triggered ...');
}
});
$('#example-deselect-onChange-array-button').on('click', function() {
$('#example-deselect-onChange-array').multiselect('deselect', '1', true);
});
});
</script>
|
.multiselect('selectAll', justVisible)
|
Selects all options. If
Note that setting
Currently, it is required to call
<script type="text/javascript">
$(document).ready(function() {
$('#example-selectAll').multiselect();
$('#example-selectAll-visible').on('click', function() {
$('#example-selectAll').multiselect('selectAll', true);
$('#example-selectAll').multiselect('updateButtonText');
});
$('#example-selectAll-all').on('click', function() {

$('#example-deselectAll-visible').on('click', function() {
$('#example-deselectAll').multiselect('deselectAll', true);
$('#example-deselectAll').multiselect('updateButtonText');
});
$('#example-deselectAll-all').on('click', function() {
$('#example-deselectAll').multiselect('deselectAll', false);
$('#example-deselectAll').multiselect('updateButtonText');
});
});
</script>
|
.multiselect('updateButtonText')
|
When manually selecting/deselecting options and the corresponding checkboxes, this function updates the text and title of the button.
Note that usually this method is only needed when using
<script type="text/javascript">
$(document).ready(function() {
$('#example-deselectAll').multiselect();
$('#example-deselectAll-visible').on('click', function() {
$('#example-deselectAll').multiselect('updateButtonText', true);
});
});
</script>
|
.multiselect('setOptions', options)
|
Used to change configuration after initializing the multiselect. This may be useful in combination with
<script type="text/javascript">
$(document).ready(function() {
var firstConfigurationSet = {
includeSelectAllOption: false,
enableFiltering: false
};
var secondConfigurationSet = {
includeSelectAllOption: false,
enableFiltering: true
};
var set = 1;
$('#example-setOptions').multiselect(firstConfigurationSet);
function rebuildMultiselect(options) {
$('#example-setOptions').multiselect('setOptions', options);
$('#example-setOptions').multiselect('rebuild');
}
$('#example-setOptions-button').on('click', function(event) {
switch (set) {
case 2:
rebuildMultiselect(firstConfigurationSet);
$(this).text('Configuration Set 2');
set = 1;
break;
case 1:

set = 2;
break;
}
});
});
</script>
|
.multiselect('disable')
|
Disable both the underlying select and the dropdown button.
<script type="text/javascript">
$(document).ready(function() {

$('#example-disable-button').on('click', function() {
$('#example-disable').multiselect('disable');
});
});
</script>
|
.multiselect('enable')
|
Enable both the underlying select and the dropdown button.
<script type="text/javascript">
$(document).ready(function() {
$('#example-enable').multiselect();
$('#example-enable-button').on('click', function() {
$('#example-enable').multiselect('enable');
});
});
</script>
|
.multiselect('dataprovider', data)
|
This method is used to provide options programmatically. See the example below.
<script type="text/javascript">
$('#example-dataprovider').multiselect();
var options = [
{label: 'Option 1', title: 'Option 1', value: '1', selected: true},
{label: 'Option 2', title: 'Option 2', value: '2'},
{label: 'Option 3', title: 'Option 3', value: '3', selected: true},
{label: 'Option 4', title: 'Option 4', value: '4'},
{label: 'Option 5', title: 'Option 5', value: '5'},
{label: 'Option 6', title: 'Option 6', value: '6', disabled: true}
];
$('#example-dataprovider').multiselect('dataprovider', options);
</script>
<select id="example-dataprovider" multiple="multiple"></select>
The method is also able to handle
<script type="text/javascript">
$('#example-dataprovider-optgroups').multiselect();
var optgroups = [
{
label: 'Group 1', children: [
{label: 'Option 1.1', value: '1-1', selected: true},
{label: 'Option 1.2', value: '1-2'},
{label: 'Option 1.3', value: '1-3'}
]
},
{
label: 'Group 2', children: [
{label: 'Option 2.1', value: '1'},
{label: 'Option 2.2', value: '2'},
{label: 'Option 2.3', value: '3', disabled: true}
]
}
];
$('#example-dataprovider-optgroups').multiselect('dataprovider', optgroups);
</script>
<select id="example-dataprovider-optgroups" multiple="multiple"></select>
You can add custom data attributes on option group children and non-grouped options:
$('#example-dataprovider-data-attributes').multiselect();
var optionsData =[
{
"label": "Option 1",
"value": 1,
"selected": true,
"attributes": {
"some-attribute": 1,
"another-attribute": false
}
},
{
"label": "Option 2",
"value": 2,
"selected": false,
"attributes": {
"some-attribute": 2
}
}
];
$("#example-dataprovider-data-attributes").multiselect('dataprovider', optionsData);
});
</script>
<select id="example-dataprovider-data-attributes" multiple="multiple"></select>
Renders as: <option value="1" label="Option 1" selected="selected" data-some-attribute="1" data-another-attribute="false"></option> <option value="2" label="Option 2" data-some-attribute="2"></option> |
.multiselect('setAllSelectedText', value)
|
This method is used to programmatically provide a new text to display in the button when all options are selected, at runtime.
<script type="text/javascript">
$('#example-set-all-selected-text').multiselect({allSelectedText: "Initial All Selected"});
$('#new-all-selected-text-btn').click(function(){
$('#example-set-all-selected-text').multiselect('setAllSelectedText', $('#new-all-selected-text-box').val());
});
</script>
|
Using the onChange configuration option, the following example asks for confirmation if deselecting an option.
<script type="text/javascript">
$(document).ready(function() {
$('#example-confirmation').multiselect({
onChange: function(element, checked) {
if (checked === true) {
//action taken here if true
}
else if (checked === false) {
if (confirm('Do you wish to deselect the element?')) {
//action taken here
}
else {
$("#example-confirmation").multiselect('select', element.val());
}
}
}
});
});
</script>
The above approach can also be adapted to be used in
<script type="text/javascript">
$(document).ready(function() {
var lastSelected = $('#example-confirmation-single option:selected').val();
$('#example-confirmation-single').multiselect({
onChange: function(element, checked) {
if (confirm('Do you wish to change the selection?')) {
lastSelected = element.val();
}
else {
$("#example-confirmation-single").multiselect('select', lastSelected);
$("#example-confirmation-single").multiselect('deselect', element.val());
}
}
});
});
</script>
Limit the number of selected options using the onChange option. The user may only select a maximum of 4 options. Then all other options are disabled.
<script type="text/javascript">
$(document).ready(function() {
$('#example-limit').multiselect({
onChange: function(option, checked) {
// Get selected options.
var selectedOptions = $('#example-limit option:selected');
if (selectedOptions.length >= 4) {
// Disable all other checkboxes.
var nonSelectedOptions = $('#example-limit option').filter(function() {
return !$(this).is(':selected');
});
nonSelectedOptions.each(function() {
var input = $('input[value="' + $(this).val() + '"]');
input.prop('disabled', true);
input.parent('li').addClass('disabled');
});
}
else {
// Enable all checkboxes.
$('#example-limit option').each(function() {
var input = $('input[value="' + $(this).val() + '"]');
input.prop('disabled', false);
input.parent('li').addClass('disabled');
});
}
}
});
});
</script>
Record the order the options are selected. When selecting an item an ordering number will be incremented and saved within the option.
<script type="text/javascript">
$(document).ready(function() {
var orderCount = 0;
$('#example-order').multiselect({
onChange: function(option, checked) {
if (checked) {
orderCount++;
$(option).data('order', orderCount);
}
else {
$(option).data('order', '');
}
},
buttonText: function(options) {
if (options.length === 0) {
return 'None selected';
}
else if (options.length > 3) {
return options.length + ' selected';
}
else {
var selected = [];
options.each(function() {
selected.push([$(this).text(), $(this).data('order')]);
});
selected.sort(function(a, b) {
return a[1] - b[1];
});
var text = '';
for (var i = 0; i < selected.length; i++) {
text += selected[i][0] + ', ';
}
return text.substr(0, text.length -2);
}
},
});
$('#example-order-button').on('click', function() {
var selected = [];
$('#example-order option:selected').each(function() {
selected.push([$(this).val(), $(this).data('order')]);
});
selected.sort(function(a, b) {
return a[1] - b[1];
});
var text = '';
for (var i = 0; i < selected.length; i++) {
text += selected[i][0] + ', ';
}
text = text.substring(0, text.length - 2);
alert(text);
});
});
</script>
Simulate single selections using checkboxes. The behavior will be similar to a multiselect with radio buttons except that the selected option can be deselected again.
<script type="text/javascript">
$(document).ready(function() {
$('#example-simulate-single').multiselect({
on: {
change: function(option, checked) {
var values = [];
$('#example-simulate-single option').each(function() {
if ($(this).val() !== option.val()) {
values.push($(this).val());
}
});
$('#example-simulate-single').multiselect('deselect', values);
}
}
});
});
</script>
Using a reset button together with a multiselect.
<script type="text/javascript">
$(document).ready(function() {
$('#example-reset').multiselect();
$('#example-reset-form').on('reset', function() {
$('#example-reset option:selected').each(function() {
$(this).prop('selected', false);
})
$('#example-reset').multiselect('refresh');
});
});
</script>
<form class="btn-group" id="example-reset-form">
<div class="btn-group">
<select id="example-reset" multiple="multiple">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
<option value="6">Option 6</option>
</select>
<button type="reset" id="example-reset-button" class="btn btn-default">Reset</button>
</div>
</form>
Multiselect can also be used in modals:
<script type="text/javascript">
$(document).ready(function() {
$('#example-modal').multiselect();
});
</script>
<button class="btn btn-default" data-toggle="modal" data-target="#example-modal-modal">Launch modal</button>
<div class="modal fade" id="example-modal-modal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title">Bootstrap Multiselect</h4>
</div>
<div class="modal-body">
<select id="example-modal" multiple="multiple">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
<option value="6">Option 6</option>
</select>
</div>
</div>
</div>
</div>
An example of using multiselect in an accordion/collapse:
Note that the overflow of the .panel needs to be visible: style="overflow:visible;". See the example below.
<script type="text/javascript">
$(document).ready(function() {
$('#example-collapse').multiselect();
});
</script>
<div class="panel-group" id="example-collapse-accordion">
<div class="panel panel-default" style="overflow:visible;">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#example-collapse-accordion" href="#example-collapse-accordion-one">
Bootstrap Multiselect
</a>
</h4>
</div>
<div id="example-collapse-accordion-one" class="panel-collapse collapse in">
<div class="panel-body">
<select id="example-collapse" multiple="multiple">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
<option value="6">Option 6</option>
</select>
</div>
</div>
</div>
</div>
The examples below are aimed to demonstrate the performance of several features when using a large number of options:
includeSelectAllOption set to true.enableFiltering set to true.enableClickableOptGroups.
The below examples need to be activated. Note that this may take some time!
Use options:
<script type="text/javascript">
$(document).ready(function() {
$('#example-large-enable').on('click', function() {
var options = $('#example-large-options').val();
if (options < 1 || options > 5000) {
$('#example-large-error').html('<p class="alert alert-error">Choose between 1 and 5000 options!</p>');
}
else {
$('#example-large-includeSelectAllOption').html('');
$('#example-large-includeSelectAllOption-enableFiltering').html('');
$('#example-large-includeSelectAllOption-enableFiltering-enableClickableOptGroups').html('');
$('#example-large-reset').html('');
for (var j = 0; j < options; j++) {
i = j + 1;
$('#example-large-includeSelectAllOption').append('<option value="' + i.toString() + '">Option ' + i.toString() + '</option>');
$('#example-large-includeSelectAllOption-enableFiltering').append('<option value="' + i.toString() + '">Option ' + i.toString() + '</option>');
var group = Math.floor(j/10) + 1;
var number = j % 10 + 1;
if (number === 1) {
$('#example-large-includeSelectAllOption-enableFiltering-enableClickableOptGroups').append('<optgroup label="Group ' + group.toString() + '"></optgroup>');
}
$('#example-large-includeSelectAllOption-enableFiltering-enableClickableOptGroups').append('<option value="' + group.toString() + '-' + number.toString() + '">Option ' + group.toString() + '.' + number.toString() + '</option>');
$('#example-large-reset').append('<option value="' + i.toString() + '">Option ' + i.toString() + '</option>');

The following examples is aimed to demonstrate the performance of the .multiselect('dataprovider', data) for a large number of options.
The below examples need to be activated. Note that this may take some time!
$(document).ready(function() {
var data = [];
for (var i = 0; i < 100; i++) {
var group = {label: 'Group ' + (i + 1), children: []};
for (var j = 0; j < 10; j++) {
group['children'].push({
label: 'Option ' + (i + 1) + '.' + (j + 1),
value: i + '-' + j
});
}
data.push(group);
}
$('#example-large-dataprovider-button').on('click', function() {
$('#example-large-dataprovider').multiselect({
maxHeight: 200
});
$('#example-large-dataprovider').multiselect('dataprovider', data);
});
});
<p class="alert alert-info"><button id="example-large-dataprovider-button" class="btn btn-primary">Activate</button></p>
<select id="example-large-dataprovider" multiple="multiple"></select>
The following example illsutrates how to disable options using JavaScript.
$(document).ready(function() {
$('#example-disable-javascript').multiselect();
});
<select id="example-disable-javascript" multiple="multiple"></select>
Performance example for using .multiselect('refresh') with a large number of options:

$(document).ready(function() {
$('#example-large-refresh-button').on('click', function() {

The following example demonstrates how to limit the number of selections of a specific optgroup:
<script type="text/javascript">
$(document).ready(function() {
$('#example-optgroup-limit').multiselect({
onChange: function(options, checked) {
var $option = $(options);
if ($option.length == 1) {
var $group = $option.parent('optgroup')
if ($group.hasClass('group-1')) {
var $options = $('option', $group);
$options = $options.filter(':selected');
if (checked && $options.length > 2) {
alert('Cannot select more than 2 elements in this group!');
$("#example-optgroup-limit").multiselect('deselect', $option.val());
}
}
}
}
});
});
</script>
<div class="btn-group">
<select id="example-optgroup-limit" multiple="multiple">
<optgroup class="group-1" label="Group 1">
<option value="1-1">Option 1.1</option>
<option value="1-2">Option 1.2</option>
<option value="1-3">Option 1.3</option>
</optgroup>
<optgroup class="group-2" label="Group 2">
<option value="2-1">Option 2.1</option>
<option value="2-2">Option 2.2</option>
<option value="2-3">Option 2.3</option>
</optgroup>
</select>
</div>
The below example demonstrates how to show the optgroup's label if all option's within this group are selected:
<script type="text/javascript">
$(document).ready(function() {
$('#example-optgroup-buttonText').multiselect({
buttonText: function(options, select) {
// First consider the simple cases, i.e. disabled and empty.
if (this.disabledText.length > 0
&& (this.disableIfEmpty || select.prop('disabled'))
&& options.length == 0) {
return this.disabledText;
}
else if (options.length === 0) {
return this.nonSelectedText;
}
var $select = $(select);
var $optgroups = $('optgroup', $select);
var delimiter = this.delimiterText;
var text = '';
// Go through groups.
$optgroups.each(function() {
var $selectedOptions = $('option:selected', this);
var $options = $('option', this);
if ($selectedOptions.length == $options.length) {
text += $(this).attr('label') + delimiter;
}
else {
$selectedOptions.each(function() {
text += $(this).text() + delimiter;
});
}
});
var $remainingOptions = $('option:selected', $select).not('optgroup option');
$remainingOptions.each(function() {
text += $(this).text() + delimiter;
});
return text.substr(0, text.length - 2);
}
});
});
</script>
<div class="btn-group">
<select id="example-optgroup-buttonText" multiple="multiple">
<optgroup class="group-1" label="Group 1">
<option value="1-1">Option 1.1</option>
<option value="1-2">Option 1.2</option>
<option value="1-3">Option 1.3</option>
</optgroup>
<optgroup class="group-2" label="Group 2">
<option value="2-1">Option 2.1</option>
<option value="2-2">Option 2.2</option>
<option value="2-3">Option 2.3</option>
</optgroup>
</select>
</div>
The following example demonstrates how to set the class of li.active's parent elements:
<script type="text/javascript">
$(document).ready(function() {
$('#example-selected-parents').multiselect({
buttonContainer: '<div id="example-selected-parents-container"></div>',
onChange: function(options, selected) {
// Get checkbox corresponding to option:
var value = $(options).val();
var $input = $('#example-selected-parents-container input[value="' + value + '"]');
// Adapt label class:
if (selected) {
$input.closest('label').addClass('active');
}
else {
$input.closest('label').removeClass('active');
}
}
});
});
</script>
<style type="text/css">
#example-selected-parents-container label.active {
font-weight: bold;
}
</style>
<div class="btn-group">
<select id="example-selected-parents" multiple="multiple">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
<option value="6">Option 6</option>
</select>
</div>
The following example demonstrates how to clear filtering as soon as an option is selected after the filter was used. Note that the filter is cleared both when an option is selected and deselected.
<script type="text/javascript">
$(document).ready(function() {
$('#example-clear-after-filter-selection').multiselect({
buttonContainer: '',
enableFiltering: true,
onChange: function($option) {
// Check if the filter was used.
var query = $('#example-clear-after-filter-selection-container li.multiselect-filter input').val();
if (query) {
$('#example-clear-after-filter-selection-container li.multiselect-filter input').val('').trigger('keydown');
}
}
});
});
</script>
The below example uses a PHP script to demonstrate Server-Side Processing. Therefore, the below example will not run online - download the repository and try it on a local server.
In order to receive the correct data after submitting the form, the used select has to have an appropriate name. Note that an [] needs to be appended to the name when using the multiple option/attribute. Per default, the checkboxes used within the multiselect will not be submitted, however, this can be changed by adapting checkboxName. The select all option as well as the text input used for the filter will not be submitted. As this may be useful, the name of the select all checkbox may be adapted using the selectAllName option. The value of the select all checkbox can be controlled by the selectAllValue option while the values of the remaining checkboxes correspond to the values used by the option's of the original select.
The plugin naturally supports the required attribute.
<script type="text/javascript">
$(document).ready(function() {
$('#example-post').multiselect({
includeSelectAllOption: true,
enableFiltering: true
});
});
</script>
<form class="form-horizontal" method="POST" action="post.php">
<div class="form-group">
<label class="col-sm-2 control-label">Multiselect</label>
<div class="col-sm-10">

<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
<option value="5">Option 5</option>
<option value="6">Option 6</option>

<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Submit</button>

</div>
</form>
The checkboxName option can also be used to assign different names to the option's, for example for different optgroups.
Note that in the below example, $_POST will contain both the multiselect and the group1 as well as group2 keys.
<script type="text/javascript">
$(document).ready(function() {
$('#example-post-checkboxName').multiselect({
checkboxName: function(option) {
var $optgroup = $(option).closest('optgroup');
if ($optgroup.id == 'example-post-checkboxName-1') {
return 'group1[]';
}
else {
return 'group2[]';
}
}
});
});
</script>
<form class="form-horizontal" method="POST" action="post.php">
<div class="form-group">
<label class="col-sm-2 control-label">Multiselect</label>
<div class="col-sm-10">
<select id="example-post-checkboxName" name="multiselect[]" multiple="multiple" required>
<optgroup label="Group 1" id="example-post-checkboxName-1">
<option value="1-1">Option 1.1</option>
<option value="1-2">Option 1.2</option>
<option value="1-3">Option 1.3</option>
</optgroup>
<optgroup label="Group 1" id="example-post-checkboxName-2">
<option value="2-1">Option 2.1</option>
<option value="2-2">Option 2.2</option>
<option value="2-3">Option 2.3</option>
</optgroup>
</select>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-2 col-sm-10">
<button type="submit" class="btn btn-default">Submit</button>
</div>
</div>
</form>
Tab |
As with other form elements, Tab is used to switch to the next form elements. Tab can be used when the dropdown is opened as well as when it is closed. |
Space/Enter |
Space or Enter is used to open the dropdown and select options. After a multiselect is in focus, pressing Space or Enter will open the dropdown. Then, the options can be traversed using arrow up and down. |
Arrow Up/Arrow Down |
Used to traverse the options after opening the dropdown. An option can be selected using Space or Enter. |
index.html) and appropriate examples should be added.return false; within the onChange option does not prevent the option from being selected/deselected ...return statement within the onChange method has no influence on the result. For preventing an option from being deselected or selected have a look at the examples in the Further Examples section.
.multiselect('select', value); or .multiselect('deselect', value);?select occurs for other elements, as well. In addition this may be caused if the multiselect has the class .multiselect. See #330.

$('#example option:selected');
// get all option element values
$('#example option:selected').map(function(a, item){return item.value;});
select:
<select id="example2" multiple="multiple" name="select[]"></select>
Or add an appropriate name to the checkboxes:
$('#example2').multiselect({
checkboxName: function(option) {
return 'multiselect[]';
}
});
.multiselect-container input {
display: none
}
$.validate?
var $form = $("#myForm");
var validator = $form.data('validator');
validator.settings.ignore = ':hidden:not(".multiselect")';
.multiselect('dataprovider', data) method?type="reset" button does not refresh the multiselect, what to do?select's in single selection mode with option's sharing values across the different select's.checkboxName:
$('.multiselect').multiselect({
checkboxName: function(option) {
return _.uniqueId('multiselect_');
}
});
where _.uniqueId('multiselect_') should be replaced with a random generator. Alternatively, a unique value for checkboxName can be used for each multiselect.

Esc will not close the dropdown as there were some bugs with this.
optionLabel option as follows:
optionLabel: function(element){
return $(element).attr('label') || $(element).html();
},
This issue was discussed in #532.
The plugin depends upon the following standard knockout bindings: options, value, selectedOptions, enable, disable. When these options change, they will update the internal select element and .multiselect('refresh') is triggered.
options: when options is an observable and changes, the option's inside the select are updated by knockout and the plugin refreshes.value: can only be used in single selection mode; Knockout does not support using the value binding handler to update a select with multiple="multiple".selectedOptions: this is a standard knockout binding that updates the checked options inside the select element; use with multiple="multiple".enable: enable the plugin.disable: disable the plugin.Any other options inside the multiselect data bind are passed to the jQuery multiselect plugin.
var $ = require('jquery');
var multiselect = require('bootstrap-multiselect');
$.multiselect = multiselect;
$("#example").multiselect();
