All pre-built files needed to use Selectize can be found in the dist folder.
If you're looking to get started with minimal fuss, include
standalone/selectize.min.js (bundles Sifter and Microplugin dependencies).
Selectize is available at cdnjs.
<script type="text/javascript" src="selectize.js"></script>
<link rel="stylesheet" type="text/css" href="selectize.css" />

$(function () {
$("select").selectize(options);
});

setting
property of the Selectize object.valueField
setting. Option objects must also have a property with the label to display (as tag, in the drop down, etc.); the property name is defined by the labelField
setting. The
options can have other properties, ignored, unless referenced by other settings, like sortField
or searchField
.
General | |||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Setting | Description | Type | Default | ||||||||||
options |
An array of the initial options available to select; array of objects. By default this is populated from the original input element. If your element is a <select> with <option>s specified this property gets populated automatically. Setting this property is convenient if you have your data as an array and want to automatically generate the <option>s. | array |
[] |
||||||||||
items |
An array of the initial selected values. By default this is populated from the original input element. | array |
[] |
||||||||||
delimiter |
The string to separate items by. When typing an item in a multi-selection control allowing creation, then the delimiter, the item is added. If you paste delimiter-separated items in such control, the items are added at once. The delimiter is also used in the getValue API call on a text <input> tag to separate the multiple values. |
string |
',' |
||||||||||
create |
Allows the user to create new items that aren't in the initial list of options. This setting can be any of the following: true , false (disabled), or a function to process input. The function can take one of two forms: synchronous (with signature function(input){} or asynchronous (with signature function(input, callback) . In the
synchronous case, the function should return an object for the options (eg, with defaults: return { 'value': value, 'text': text }; ). The asynchronous version should invoke the callback with the result in the same format as the object above (eg, callback( { 'value': value, 'text': text}); )

render |
Custom rendering functions. Each function should accept two arguments: data and escape and return HTML (string or DOM element) with a single root element. The escape argument is a function that takes a string and escapes all special HTML characters. This is very important to use to prevent XSS vulnerabilities.
|
object |
Selectize controls can be controlled programmatically via the methods
described in this section. When initializing the control, the
selectize
property is added on the original <select> /
<input> element—this property points to the underlying Selectize
instance.
// initialize the Selectize control
var $select = $('select').selectize(options);
// fetch the instance
var selectize = $select[0].selectize;
Property | Description |
---|---|
options |
An object containing the entire pool of options. The object is keyed by each object's value. |
items |
An array of selected values. |
Options | ||

Method | Description | |
addOption(data) |
Adds an available option, or array of options. If it already exists, nothing will happen. Note: this does not refresh the options list dropdown (use refreshOptions() for that). | |
updateOption(value, data) |
Updates an option available for selection. If it is visible in the selected items or options dropdown, it will be re-rendered automatically. | |
removeOption(value) |
Removes the option identified by the given value. | |
clearOptions(silent) |
Removes all options from the control, and resets/clears all selected
items. If silent is truthy, no change event will be
fired on the original input.
|
|
getOption(value) |
Retrieves the jQuery element for the option identified by the given value. | |
getAdjacentOption(value, direction) |
Retrieves the jQuery element for the previous or next option,
relative to the currently highlighted option. The
direction argument should be 1 for "next" or -1 for
"previous".
|
|
refreshOptions(triggerDropdown) |
Refreshes the list of available options shown in the autocomplete dropdown menu. | |
Items | ||
Method | Description | |
clear(silent) |
Resets / clears all selected items from the control. If
silent is truthy, no change event will be fired on the
original input.
|
|
getItem(value) |
Returns the jQuery element of the item matching the given value. | |
addItem(value, silent) |
"Selects" an item. Adds it to the list at the current caret
position. If silent is truthy, no change event will be
fired on the original input.
|
|
removeItem(value, silent) |
Removes the selected item matching the provided value. If
silent is truthy, no change event will be fired on the
original input.
|
|
createItem(value, [triggerDropdown], [callback])

Invokes the create method provided in the Selectize
settings that should provide the data for the new item, given the
user input. Once this completes, it will be added to the item list.
|
|
refreshItems() |
Re-renders the selected item lists. | |
Optgroups | ||
Method | Description | |

lock() |
Disables user input on the control (note: the control can still receive focus). | |

disable() |
Disables user input on the control completely. While disabled, it cannot receive focus. | |
enable() |
Enables the control so that it can respond to focus and user input. | |
getValue() |
Returns the value of the control. If multiple items can be selected
with a "select" input tag (e.g.
<select multiple>), this returns an array. Otherwise, returns a string (separated by
delimiter if "multiple").
|
|
setValue(value, silent) |
Resets the selected items to the given value. | |
setCaret(index) |
Moves the caret to the specified position (index being

Via the microplugin interface, features can be added to Selectize without modifying the main library. This is great because it protects against code bloat, allows for lean builds, and allows for addons to be sanely isolated. The plugin system isn't meant to be sexy; it's lean, makes very few assumptions, and gives the developer complete control.
A few notes:
/[a-z_]+$
setup()
method.Selectize.define('plugin_name', function(options) {
// options: plugin-specific options
// this: Selectize instance
});
Selectize.define('plugin_name', function(options) {
this.require('another_plugin');
});
Methods should be extended by wrapping them:
var self = this;
this.someMethod = (function() {
var original = self.someMethod;
return function() {
// do your logic
return original.apply(this, arguments);
};
})();
Because all elements for the control are created within the
setup()
method (which is invoked after the plugin initialized)
events should be added by overriding the setup method, like so:
Selectize.define('plugin_name', function(options) {
var self = this;
// override the setup method to add an extra `click` handler
this.setup = (function() {
var original = self.setup;
return function() {
original.apply(this, arguments);
this.$control.on('click', 'div', function(e) {
alert('A div was clicked!');
});
};
})();
