Create a styled Dropdown like on jquery UI

On http://jqueryui.com/demos/accordion/ at the top right corner, you can see a dropdown tha开发者_Python百科t says "Theme: UI Lightness" by default.

I'd love to create such an interactive element in my web application. Does anyone know of a good jquery plugin to easily do this?

A nice example of a plugin exists here. Enabled by nothing more than $('select').selectmenu();.
