Bootstrap Multiselect is a JQuery based plugin to provide an intuitive user interface for using select inputs with the multiple attribute present. Instead of a select a bootstrap button will be shown as dropdown menu containing the single options as checkboxes.

The demonstration page for Bootstrap 2.3.x was removed. Nevertheless, this page should be working with Bootstrap 2.3.x as well except for some methods which are marked accordingly.

Please have a look at the Contribution Guidelines and the Issue Tracker.

The following code snippet will help you getting started.

<!-- 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"/>

<!-- Build your select: -->
<select class="multiselect" 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>

<!-- Initialize the plugin: -->
<script type="text/javascript">
$(document).ready(function() {
    $('.multiselect').multiselect();
});
</script>
            

The best way learning from the examples is using firebug, chrome developer tools or similar tools for your browser. Examine the generated markup and used javascript code.

Normal select. The plugin will do single selection using radio buttons rather than multiple selection using checkboxes.
Single selection without having the browser select the first option.
The `.multiselect('select', value, triggerOnChange)` method can also be used to select options in single selection mode. Of course, the `.multiselect('deselect', value, triggerOnChange)` method works as expected, as well.
Select with preselected options: <option value="cheese" selected>Cheese</option>
Multiselect with a 'Select all' option.
Multiselect with a 'Select all' option and filtering enabled using the enableFiltering option.
The 'Select all' option automatically repsonds to the selection of the user. In particular, it responds to the initial state of the select.
Test the performance of the 'Select all' option with 999 options.
As link using buttonClass: 'btn btn-link'.
Small button using buttonClass: 'btn btn-default btn-sm'.
Multiple select within a group with add-ons and default container for the plugin: buttonContainer: '<div class="btn-group" />'.
Using the onChange option you can add an event handler to the change event. The event handler gets the selected option as first parameter and a variable saying whether the option is checked or not as second one.
For long option lists the maxHeight option can be set.
The plugin supports disabled options, too: disabled="disabled"
Use the buttonWidth option to adjust the width of the button.
Using the onChange option to prevent user from deselecting selected options.
Option groups are detected automatically and for each option group an header element is added: <optgroup label="Mathematics">...</optgroup>
Option groups and options without any group are supported simultaneously.
Using the selectedClass option to turn off the active class for selected options.
Specify an alternative label for the options: <option label="label"></option>
Make the menu drop right instead of dropping left with dropRight.
Using the data-role="multiselect" attribute for automatic wireup.
The multiselect will adopt the state of the select: <select disabled></select>.
The button will keep the tabindex of the select.
Using optgroupss with filtering and the select all option.
Use the checkboxName to adapt the name attribute of the used checkboxes.

Automatically disable multiselect if it has no options.

Option Explanation Usage
buttonText A function returning the string displayed if options are selected. All currently selected options and the select are passed as argument. In addition HTML can be added to the button, for example the caret icon seen in the examples.
<script type="text/javascript">
$(document).ready(function() {
    $('.multiselect').multiselect({
        buttonText: function(options, select) {
            if (options.length == 0) {
                return this.nonSelectedText + ' <b class="caret"></b>';
            }
            else {
                if (options.length > this.numberDisplayed) {
                    return options.length + ' ' + this.nSelectedText + ' <b class="caret"></b>';
                }
                else {
                    var selected = '';
                    options.each(function() {
                        var label = ($(this).attr('label') !== undefined) ? $(this).attr('label') : $(this).html();

                        selected += label + ', ';
                    });
                    return selected.substr(0, selected.length - 2) + ' <b class="caret"></b>';
                }
            }
        }
    });
});
</script>

    $('.multiselect').multiselect({
        numberDisplayed: 4
    });
});
</script>

    $('.multiselect').multiselect({
        nonSelectedText: 'You have not selected any options'
    });
});

                selected += $(this).text() + ', ';
            });
            return selected.substr(0, selected.length - 2);
        },
    });
});

The plugin uses templates to create different parts of the plugin - as for example the filter, dividers or the button. The default templates can be seen below.

templates: {
    button: '<button type="button" class="multiselect dropdown-toggle" data-toggle="dropdown"></button>',
    ul: '<ul class="multiselect-container dropdown-menu"></ul>',
    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: '<li><a href="javascript:void(0);"><label></label></a></li>',
    divider: '<li class="divider"></li>',
    liGroup: '<li><label class="multiselect-group"></label></li>'
}
            

The templates can be overriden using the templates configuration option. The example below uses a div for dividers.

<script type="text/javascript">
$(document).ready(function() {
    $('.multiselect').multiselect({
        templates: {
            divider: '<div class="divider" data-role="divider"></div>'
        }
    });
});
</script>
                            

.multiselect('destroy')

This method is used to destroy the plugin on the given element - meaning unbinding the plugin.

.multiselect('refresh')

This method is used to refresh the checked checkboxes based on the currently selected options within the select. Click 'Select some options' so select some of the options (meaning added the selected attribute to some of the options). Then click refresh. The plugin will update the checkboxes accordingly.

.multiselect('rebuild')

Rebuilds the whole dropdown menu. All selected options will remain selected (if still existent!).

.multiselect('select', value, triggerOnChange)

Selects an option by its value. Works also using an array of values. If triggerOnChange is set to true, the onChange event is triggered.

.multiselect('deselect', value)

Deselect an option by its value. Works also using an array of values. If triggerOnChange is set to true, the onChange event is triggered.

.multiselect('dataprovider', data)

Provides data for building the select's options the following way:

var data = [
    {label: 'Cheese', value: 'cheese'},
    {label: 'Tomatoes', value: 'tomatoes'}
];
$("#multiselect").multiselect('dataprovider', data);
                            

Alternatively, this method can also be used to build option groups (#281):

var data = [
    {title: 'First group', children: [{label: 'Cheese', value: 'cheese'}, {label: 'Tomatoes', value: 'tomatoes'}]},
    {title: 'Second group', children: [{label: 'Mozzarella', value: 'mozzarella'}, {label: 'Mushrooms', value: 'mushrooms'}]},
];
$('.multiselect').multiselect('dataprovider', data);
                            

.multiselect('setOptions', options)

Used to change configuration after initializing the multiselect. This may be useful in combination with .multiselect('rebuild'). See the Further Examples section for an example.

.multiselect('disable')

Disable both the underlying select and the dropdown button.

.multiselect('enable')

Enable both the underlying select and the dropdown button.

Use "Select" and "Deselect" to select or deselect cheese and tomatoes. Use "Values" to display the currently selected elements by using $('.multiselect').val().

<script type="text/javascript">
$('#example34').multiselect();

$('#example34-select').on('click', function() {
$('#example34').multiselect('select', 'cheese');
$('#example34').multiselect('select', 'tomatoes');
});

$('#example34-deselect').on('click', function() {
$('#example34').multiselect('deselect', 'cheese');
$('#example34').multiselect('deselect', 'tomatoes');
});

$('#example34-values').on('click', function() {
$('#example34-text').text('Selected: ' + $('#example34').val()).addClass('alert alert-info');
});
</script>
                            

Use the button to toggle the selection.

<script type="text/javascript">
/**
 * Gets whether all the options are selected
 * @param {jQuery} $el
 * @returns {bool}
 */
function multiselect_selected($el) {
    var ret = true;
    $('option', $el).each(function(element) {
        if (!!!$(this).prop('selected')) {
            ret = false;
        }
    });
    return ret;
}

/**
 * Selects all the options
 * @param {jQuery} $el
 * @returns {undefined}
 */
function multiselect_selectAll($el) {
    $('option', $el).each(function(element) {
        $el.multiselect('select', $(this).val());
    });
}
/**
 * Deselects all the options
 * @param {jQuery} $el
 * @returns {undefined}
 */
function multiselect_deselectAll($el) {
    $('option', $el).each(function(element) {
        $el.multiselect('deselect', $(this).val());
    });
}

/**
 * Clears all the selected options
 * @param {jQuery} $el
 * @returns {undefined}
 */
function multiselect_toggle($el, $btn) {
    if (multiselect_selected($el)) {
        multiselect_deselectAll($el);
        $btn.text("Select All");
    }
    else {
        multiselect_selectAll($el);
        $btn.text("Deselect All");
    }
}

$(document).ready(function() {
    $('#example21').multiselect();
    $("#example21-toggle").click(function(e) {
        e.preventDefault();
        multiselect_toggle($("#example21"), $(this));
    });
});
</script>
                            

When deselecting an option you will be asked for confirmation.

<script type="text/javascript">
$(document).ready(function() {
    $('#example22').multiselect({
        buttonClass: 'btn',
        buttonWidth: 'auto',
        buttonText: function(options) {
            if (options.length == 0) {
                return 'None selected <b class="caret"></b>';
            }
            else if (options.length > 6) {
                return options.length + ' selected  <b class="caret"></b>';
            }
            else {
                var selected = '';
                options.each(function() {
                    selected += $(this).text() + ', ';
                });
                return selected.substr(0, selected.length -2) + ' <b class="caret"></b>';
            }
        },
        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 {
                    $("#example22").multiselect('select', element.val());
                }
            }
        }
    });
});
</script>
                            

Switching between different configuration sets is possible using a combination of .multiselect('setOptions', options) and .multiselect('rebuild').

<script type="text/javascript">
$(document).ready(function() {

    var firstConfigurationSet = {
        includeSelectAllOption: false,
        enableFiltering: false
    };
    var secondConfigurationSet = {
        includeSelectAllOption: true,
        enableFiltering: true
    };

    var set = 1;
    $('#example33').multiselect(firstConfigurationSet);

    function rebuildMultiselect(options) {
        $('#example33').multiselect('setOptions', options);
        $('#example33').multiselect('rebuild');
    }

    $('#example33-configuration-set').on('click', function(event) {
        switch (set) {
            case 2:
                rebuildMultiselect(firstConfigurationSet);

                $(this).text('Configuration Set 2');
                set = 1;
                break;
            case 1:
            default:
                rebuildMultiselect(secondConfigurationSet);

                $(this).text('Configuration Set 1');
                set = 2;
                break;
        }
    });
});
</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() {
    $('#example37').multiselect({
        onChange: function(option, checked) {
            // Get selected options.
            var selectedOptions = $('#example37 option:selected');

            if (selectedOptions.length >= 4) {
                // Disable all other checkboxes.
                var nonSelectedOptions = $('#example37 option').filter(function() {
                    return !$(this).is(':selected');
                });

                var dropdown = $('#example37').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 = $('#example37').siblings('.multiselect-container');
                $('#example37 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;
    $('#example38').multiselect({
        buttonText: function(options) {
            if (options.length == 0) {
                return 'None selected ';
            }
            else if (options.length > 3) {
                return options.length + ' selected  ';
            }
            else {
                var selected = [];
                options.each(function() {
                    selected.push([$(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) + ' ';
            }
        },
        onChange: function(option, checked) {
            if (checked) {
                orderCount++;
                $(option).data('order', orderCount);
            }
            else {
                $(option).data('order', '');
            }
        }
    });

    $('#example38-order').on('click', function() {
        var selected = [];
        $('#example38 option:selected').each(function() {
            selected.push([$(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.

<script type="text/javascript">
$('#example40').multiselect({
    onChange: function(option, checked) {
        var values = [];
        $('#example40 option').each(function() {
            if ($(this).val() !== option.val()) {
            values.push($(this).val());
            }
        });

        $('#example40').multiselect('deselect', values);
    }
});
</script>
                            

Close dropdown after 3 selections automatically.

<script type="text/javascript">
$('#example42').multiselect({
    onChange: function(option, checked) {
        var selected = 0;
        $('option', $('#example42')).each(function() {
            if ($(this).prop('selected')) {
                selected++;
            }
        });

        if (selected >= 3) {
            $('#example42').siblings('div').children('ul').dropdown('toggle');
        }
    }
});
</script>
                            

Trigger hide.bs.dropdown and show.bs.dropdown manually.

<script type="text/javascript">
$('#example40').multiselect({
    onChange: function(option, checked) {
        var values = [];
        $('#example40 option').each(function() {
            if ($(this).val() !== option.val()) {
                values.push($(this).val());
            }
        });

        $('#example40').multiselect('deselect', values);
    }
});
</script>
                            

Using a reset button together with a multiselect.

$('#example52').multiselect();
$('#example52-form').on('reset', function() {
    $('#example52 option').each(function() {
        $(this).prop('selected', false);
    })

    $('#example52').multiselect('refresh');
});
                            

For additional styling of the multiselect button, the CSS class multiselect can be used.

Text alignment combined with fixed width and bold, underlined text for option group headers.

.multiselect {
    text-align: left;
}
.multiselect b.caret {
    position: absolute;
    top: 14px;
    right: 8px;
}
.multiselect-group {
    font-weight: bold;
    text-decoration: underline;
}
                        

Access the select all option by using the .multiselect-all class. The filter search field can be manipulated by using .multiselect-search;

.multiselect-all label {
    font-weight: bold;
}
.multiselect-search {
    color: red;
}
                        

Here are some of the (not necessarily that frequently) asked questions and their answers.

What about older browsers, i.e. Internet Explorer 6, 7 and 8?

With version 2.0, jQuery no longer supports the older IE versions. Nevertheless, the plugin should run as expected using the 1.x branch of jQuery. See here for details.

Using return false; within the onChange option does not prevent the option from being selected/deselected ...

The 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.

How to check whether filtering all options resulted no options being displayed (except the select all option)?

This issue is discussed here: https://github.com/davidstutz/bootstrap-multiselect/issues/317.

How to get the selected options using PHP?

This issue is addressed here: https://github.com/davidstutz/bootstrap-multiselect/issues/323.

Mainly there are two ways, either add a name to the select:

or add an appropriate name to the checkboxes:

$('#example2').multiselect({
checkboxName: 'multiselect[]'
});
            

How to change the button class depending on the number of selected options?

This issue is addressed here: https://github.com/davidstutz/bootstrap-multiselect/issues/332.

Why does the plugin crash when using .multiselect('select', value); or .multiselect('deselect', value);?

This may be caused when the class used for the select occurs for other elements, as well. In addition this may be caused if the multiselect has the class .multiselect. See here: https://github.com/davidstutz/bootstrap-multiselect/issues/330.

How to use multiple plugin instances running single selections on one page?

There is a minor bug when using multiple plugin instances with single selection on one page. The bug is described here: https://github.com/davidstutz/bootstrap-multiselect/issues/331. A possible fix is suggested here: https://github.com/davidstutz/bootstrap-multiselect/pull/336.

A type="reset" button does not refresh the multiselect, what to do?

Have a look at the Further Examples section (in addition, issue 360 discussed this).

Using multiple select's in single selection mode with option's sharing values across the different select's.

This issue is discussed in detail here: #362. A simple solution is to use different option values for the option 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.
