Listbox.js is a simple jQuery plugin that provides a more powerful alternative to the standard <select> tag. The main problem of <select tag is that last one isn't flexible for customization with CSS. Listbox.js solves this problem. This component runs on top of <select> tag and creates an alternative to the last one based on <div> tags. It opens up great possibilities for customization.

In addition, this component provides the search bar which would be useful in lists with a lot of items.

This component was born special for XSnippet project.

NOTE: This is my first JavaScript code. So don't judge strictly.

Link the component and a stylesheet from your page.

<!-- make sure that jQuery is already included -->
<script src="/path/to/jquery.js"></script>

<!-- include listbox plugin and default stylesheet -->
<link href="/path/to/listbox.css" rel="stylesheet">
<script src="/path/to/listbox.js"></script>

Create Listbox object.

<select>
  <option>Item #1</option>
  <option>Item #2</option>
  <option>Item #3</option>
  <option>Item #4</option>
</select>

<script>
    $(function() {
        $('select').listbox({
            'class':      'myOwnClass',
            'searchbar':  true
        });
    });
</script>

Listbox.js uses following CSS classes.

.lbjs {}                        /* <div>: component container */
.lbjs-list {}                   /* <div>: container for list items */
.lbjs-item {}                   /* <div>: list item */
.lbjs-item:not([disabled]) {}   /* <div>: enabled list item */
.lbjs-item[disabled] {}         /* <div>: disabled list item */
.lbjs-item[selected] {}         /* <div>: selected list item */
.lbjs-searchbar {}              /* <input>: search query input */

• How to bind event handler to the `click` list item event?

  Because of Listbox.js dynamically changes DOM you should use jQuery's live() method:

  $('.myListboxClass .lbjs-item').live('click', function() {
      alert($(this).html());
  });

• How to make disabled item?

  The process is similar to making disabled items in the <select>-tag. All you need is to set the disabled attribute.

  $('.myOwnClass .lbjs-item').each(function () {
      var value = $(this).html();
  
      if (['PHP', 'JavaScript'].indexOf(value) != -1)
          $(this).attr('disabled', '');
  });
