Answer 18

Here are several jQuery plugin's that I've found to be excellent and broadly useful:

1. jqGrid - a powerful AJAX enabled grid with support for editing, sorting, async loading, and much more.
2. FlexBox - a dropdown box replacement with support for combobox behavior and ajax functionality.
3. Superfish - a plugin that helps with the creations of semantic, css-only vertical/horizontal menus.
4. Collapsible Div - pretty much what the name says; support animation, events, and accordion behavior.
