How to use it:

1. Import jQuery library and the jQuery Dropdown.js plugin's files into the html document.

<script src="//code.jquery.com/jquery.min.js"></script>
<link rel="stylesheet" href="jquery.dropdown.css">
<script src="jquery.dropdown.js"></script>

2. Create a normal select box with 'display:none' CSS property.

<div class="demo">
  <select style="display:none"  name="" multiple>
    <option value="1" selected>1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
    <option value="5">5</option>
    <option value="3" selected>Selected</option>
    <option value="4" disabled>Disabled</option>
    <option value="5">5</option>
    <option value="6">6</option>
    ...
  </select>
</div>

$('.demo').dropdown({
  // options here
});

4. You're also allows to dynamically render the options data using JSON & JS array:

<div class="demo">
  <select style="display:none" name="" id="" multiple></select>
</div>
$('.demo').dropdown({
  data: [//data here]
});

5. Convert the select box into a tag/token manager.

$('.demo').dropdown({
  multipleMode: 'label'
});

6. All default customization options:

$('.demo').dropdown({

  // read only
  readOnly: false,

  // min count
  minCount: 0,

  // error message
  minCountErrorMessage: '',

  // the maximum number of options allowed to be selected
  limitCount: Infinity,

  // search field
  input: '<input type="text" maxLength="20" placeholder="Search">',

  // dynamic data here
  data: [],

  // is search able?
  searchable: true,

  // when there's no result
  searchNoData: '<li style="color:#ddd">No Results</li>',

  // callback
  init: noop,

  // callback
  choice: function () {},

  // custom props
  extendProps: []

});
