Flexible Context Menus: Jeegocontext

Jeegoocontext is a jQuery plugin for creating highly customizable context menus.

It transforms unordered lists into multi-level, smartly positioned navigations.

Multiple context menus can be created on the same page & they can be customized via CSS.

It has customizable time-delays for submenus' disappear values which makes browsing them easier.

The plugin also has a workaround for Opera not allowing right-click overrides & works with it as well.
