Basic Usage:

1. Include jQuery library and selectize.js in the head section

<script src="/path/to/jquery.min.js"></script>
<script src="/path/to/selectize.js"></script>

2. Include jQuery selectize CSS to style the plugin

<link rel="stylesheet" href="selectize.css">

3. Create a container for the tags input

<input type="text" id="input-tags" class="demo-default" value="awesome,neat">

4. Call the function on the input field to initialize the plugin.


  // 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.
  options: [],

  // Initial selected values.
  items: []

  // Option groups that options will be bucketed into. 
  // If your element is a <select> with <optgroup>s this property gets populated automatically. 
  // Make sure each object in the array has a property named whatever optgroupValueField is set to.
  optgroups: [],

  // Custom delimiter character to separate items
  delimiter: ',',

  // All plugins live in their own folders in "src/plugins".
  plugins: [],

  // regexp or string for splitting up values from a paste command
  splitOn: null, 

  // If false, items created by the user will not show up as available options once they are unselected.
  persist: true,

  // Enable or disable international character support.
  diacritics: true,

  // 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});)
  create: false,

  // If true, when user exits the field (clicks outside of input), a new option is created and selected (if create setting is enabled).
  createOnBlur: false,

  // Specifies a RegExp or a string containing a regular expression that the current search filter must match to be allowed to be created. 
  // May also be a predicate function that takes the filter text and returns whether it is allowed.
  createFilter: null,

  // Toggles match highlighting within the dropdown menu.
  highlight: true,

  // Show the dropdown immediately when the control receives focus.
  openOnFocus: true,

  // If true, the "Add..." option is the default selection in the dropdown.
  addPrecedence: false,

  // If true, the tab key will choose the currently selected item.
  selectOnTab: false,

  // If true, the load function will be called upon control initialization (with an empty search). Alternatively it can be set to 'focus' to call the load function when control receives focus.
  preload: false,

  // Allows empty options.
  allowEmptyOption: false,

  // Shows empty option in the dropdown
  showEmptyOptionInDropdown: false,

  // Label for empty option

  copyClassesToDropdown: true,

  //  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.
