[jQuery] Plugin help: need dropdown (stylable in IE)

Hello,

Searching for dropdown in the plugin repository yields dozens of results, most of which have no comments. So I'm hoping someone out there with experience using the kind of plugin I need can chime in. :)

Currently I have a SELECT field that contains theme names. Upon choosing a value in the select, the user hits a submit button and the page reloads, now with the new theme var being used to load the right CSS file.

This presents a problem because we've customized the dropdown area (see attached image), and IE6 (which we need to support) doesn't let you style select boxes - you're stuck with the gray arrow and ugly outline, etc.

I assume the only way to handle this is to do a JS solution, so I'm looking for a good, stylable dropdown plugin. It doesn't need to do anything fancy like multiple select.

Thanks!
