Chosen for WordPress free WordPress plugin

This plugin implements the Chosen jQuery Plugin for WordPress. Chosen makes long, unwieldy select boxes much more user-friendly. This plugin applies Chosen to any select box in your post and page content. The relevant Javascript & CSS files are only loaded if the post in question includes a select box or a [contact-form] shortcode. The Grunion Contact Form & Contact Form 7 plugins both use a the [contact-form] shortcode. If you need to force the Chosen script & styles to load on a page, simply include [chosen] within the page.
