Selectboxize is a simple and lightweight JavaScript library for styling and replacing default selectboxes. The library is heavily based on previous work by Krzysztof Suszyński.

Just add jQuery and the following dependencies to your site:

<script src="selectboxize.js"></script>
<link rel="stylesheet" type="text/css" href="selectboxize.css">

Selectboxize needs to be called on a jQuery node to replace selectboxes, like this:

$('#demo-selectbox').selectboxize();

Selectboxize call can take an optional parameter -- an object of key / value settings:

• theme (default: "selectboxize") - name of the colour theme prefixing class names applied to replaced selectboxes.
• commonClass (default: "selectboxize-replaced") - class name that is applied to root element of all replaced selectboxes.
• listboxMaxSize (default: 15) - maximum number of displayed items in rolled out selectbox without a scrollbar.
• replaceInvisible (default: false) - replace selectboxes even if they are not displayed (e.g. with display: none applied).
• callback (default: null) - function that runs after a new item has been selected.

Take a look at the following example, where there is a simple selectbox in HTML:

<select name="country">
  <option value="1">Slovakia</option>
  <option value="2">Sweden</option>
</select>

By running the example the selectbox will be changed into a bunch of HTML nodes and can be styled as such:

<div class="selectboxize-list selectboxize-replaced" data-selection="0">
  <a href="#" class="selectboxize-list-more"></a>
  <div class="selectboxize-list-list">
    <span class="selectboxize-list-item" data-item="0" data-value="1">Slovakia</span>
    <span class="selectboxize-list-item" data-item="1" data-value="2">Sweden</span>
  </div>
  <span class="selectboxize-list-current">Slovakia</span>
</div>

If you have any grand ideas on how to improve Selectboxize and make it more useful or found any bugs, just create an issue or fork the project.
