jQuery Multilevel self-resizing image-sprite shadow DropDown menu horizontal from left to right with shadow support for IE 8

The menu is using the mouseenter and mouseleave event with a timeout of 250ms for resizing itself.

This menu is inspired by the logitech.com website menu wich supports only 3 levels. With this menu you can use more levels.

Used images are remaked with Fireworks. The big background image has a DropShadow 8px 20px 85% black 270°. And for the navigation image DropShadow 8px 16px 100% #333333 270°.
