Image Combo Box
Marghoob Suleman’s Javascript Combo Box plugin is a great way to sexy-up your combo boxes within forms. Functionality includes creating combo boxes as images entirely, as well as including images per option. Basically, you can skin the standard combo box.
jQuery DropDown Checklist
This neat jQuery Dropdown Check List widget converts the standard SELECT html element into a nice dropdown with multi tickable options.
McDropDown
Am quite fond of this implementation. As you can see in the screenshot above, McDropDown nicely creates a nested menu of elements to choose from from a simple dropdown. It generates the data from a standard <ul> and <li> implementation and has a huge bunch of options to go with it. Worth checking out.
