# Bootstrap Multiselect
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.
**Note:** The option names may have changed due to the latest updates.
## Demo
A demo of different configurations can be found [here](http://davidstutz.github.com/bootstrap-multiselect/).

## Configuration Options
**buttonClass**
Define the appearance of the button using classes. See the [Bootstrap documentation](http://twitter.github.com/bootstrap/base-css.html#buttons) for more information.
$(document).ready(function() {
$('.multiselect').multiselect({
buttonClass: 'btn btn-small'
});
});
**buttonWidth**
The width of the dropdown button.
$(document).ready(function() {
$('.multiselect').multiselect({
buttonWidth: 'auto', // Default
});
});
The width can be defined using all formats accepted by CSS:
100px
50%
auto
**buttonText**
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({
buttonText: function(options) {
if (options.length == 0) {
return 'None selected <b class="caret"></b>';
}
else if (options.length > 3) {
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>';
}
},
});
});
**buttonContainer**
The used container holding both the dropdown button and the dropdown menu.
$(document).ready(function() {
$('.multiselect').multiselect({
buttonContainer: '<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);
}
});
});
**maxHeight**
Define the maximum height property of the dropdown list. If the maximum height of the option list is exceeded a scrollbar will be displayed.
$(document).ready(function() {
$('.multiselect').multiselect({
// Or false for no maximum height.
maxHeight: 400,
});
});
## Methods
**.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.
**.multiselect('rebuild')**
Rebuilds the whole dropdown menu. Selected options will still be selected.
## Knockout JS Support
Thanks to [Devristo](https://github.com/Devristo) this plugin supports [Knockout JS](http://knockoutjs.com/). For further discussion see [the pull requests](https://github.com/davidstutz/bootstrap-multiselect/pull/17).
**Define select input**
Note the multiselect: true binding!
<select class="multiSelect" data-bind="multiselect: true, options: Options, selectedOptions: SelectedOptions, optionsValue: $data" multiple="multiple"></select>
**Initialize Bootstrap-multiselect**
$(".multiSelect").multiselect();
**Apply Knockout view model**
As usual.
**Notes**
It is important to initialize the multiselect before applying the view model, since the custom binding code will hook into the onChange method to update the binding.
## Roadmap / Todo
* 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.

## Configuration Options
**buttonClass**
Define the appearance of the button using classes. See the [Bootstrap documentation](http://twitter.github.com/bootstrap/base-css.html#buttons) for more information.

$('.multiselect').multiselect({
buttonClass: 'btn btn-small'
});
});
**buttonWidth**
The width of the dropdown button.

});
The width can be defined using all formats accepted by CSS:

If the width is defined using CSS the option should be set to false.
**buttonText**

$(document).ready(function() {
$('.multiselect').multiselect({
buttonText: function(options) {
if (options.length == 0) {

}
else if (options.length > 3) {
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>';
}
},
});
});
**buttonContainer**
The used container holding both the dropdown button and the dropdown menu.
$(document).ready(function() {
$('.multiselect').multiselect({

onChange:function(element, checked){
alert('Change event invoked!');
console.log(element);
}
});
});
**maxHeight**
Define the maximum height property of the dropdown list. If the maximum height of the option list is exceeded a scrollbar will be displayed.

$('.multiselect').multiselect({
// Or false for no maximum height.
maxHeight: 400,
});
});
## Methods

## Additional Styling
Additional Styling can be done using the multiselect class:

}

float: right;
}

Normal select. The plugin will add the <code>multiple="multiple"</code> attribute automatically. The first option is selected automatically by the browser when ommitting the <code>multiple</code> attribute.
