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.

The generated HTML markup can be controlled using templates. Basically, templates are simple configuration options. The default templates are shown below:
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>'

<select id="example-dataprovider-optgroups" multiple="multiple"></select>
|
.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>
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');
});
var dropdown = $('#example-limit').siblings('.multiselect-container');
nonSelectedOptions.each(function() {
var input = $('input[value="' + $(this).val() + '"]');
input.prop('disabled', true);
input.parent('li').addClass('disabled');
});
}
else {
// Enable all checkboxes.
var dropdown = $('#example-limit').siblings('.multiselect-container');
$('#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>');
}
$('#example-large-includeSelectAllOption').multiselect({
maxHeight: 200,
includeSelectAllOption: true
});
$('#example-large-includeSelectAllOption-enableFiltering').multiselect({
maxHeight: 200,
includeSelectAllOption: true,
enableFiltering: true
});
$('#example-large-includeSelectAllOption-enableFiltering-enableClickableOptGroups').multiselect({
maxHeight: 200,
includeSelectAllOption: true,
enableFiltering: true,
enableClickableOptGroups: true
});
$('#example-large-reset').multiselect({
maxHeight: 200,
includeSelectAllOption: true
});
$('#example-large-reset-form').on('reset', function() {
$('#example-large-reset').multiselect('deselectAll', false);
$('#example-large-reset').multiselect('updateButtonText');
});
}
});
});

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

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.
form.form-inline?select:
<select id="example2" multiple="multiple" name="select[]"></select>
Or add an appropriate name to the checkboxes:
$('#example2').multiselect({
checkboxName: '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: _.uniqueId('multiselect_')
});
where _.uniqueId('multiselect_') should be replaced with a random generator. Alternatively, a unique value for checkboxName can be used for each multiselect.
TypeError: Cannot read property "toString" of ...?null or undefined is provided as argument of .multiselect('select', value) or .multiselect('deselect', value), see #386.
Esc will not close the dropdown as there were some bugs with this.
