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.
A demo of different configurations can be found here.
These examples can also be seen in action in index.html:

button
Define the appearance of the button using classes. See the Bootstrap documentation for more information.
$(document).ready(function() {
$('.multiselect').multiselect({
'none': 'select something...'
});
});
width
The width of the dropdown button.
$(document).ready(function() {
$('.multiselect').multiselect({
'width': 'auto', // Default
});
});
The width can be defined using all formats accepted by CSS:
100px
50%
auto
text
Defining the text of the button. Must be a function returning a string. All currently selected options are passed as parameter.
$(document).ready(function() {
$('.multiselect').multiselect({
'text': 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 += $(this).text() + ', ';
});
return selected.substr(0, selected.length -2);
}
},
});
});
container
The used container holding both the dropdown button and the dropdown menu.
$(document).ready(function() {
$('.multiselect').multiselect({
container: '<span class="dropdown" />',
});
});
onchange
Assign an event handler to the change event:
$(document).ready(function() {
$('.multiselect').multiselect({
onchange:function(element, checked){
alert('Change event invoked!');
console.log(element);
}
});
});
.multiselect('destroy')
This method will destroy - unbind - the plugin on the given element(s).
.multiselect('refresh')
Refresh the selected elements depending on the selected options within the select.
- This solution for multiple selects is not usable for mobile devices (especially with touchscreen). ALternatives: Using Popovers instead of Dropdowns or checking for mobile devices and displaying normal select field (one row) for mobile devices.
