Advanced jQuery Suckerfish Menu: Superfish

Superfish is an advanced suckerfish menu plugin for jQuery.

It turns a standard CSS dropdown menu and tranforms it to a more powerful one (it gracefully degrades).

It supports both horizontal & vertical menus and unlimited sub-menus can be defined.

Considering the menu is generated from a CSS-dropdown menu, every sub can be easily styled too.

Other features of Superfish:

• Suckerfish-style hover support for IE6.
• Timed delay on mouseout.
• Animation of sub-menu reveal.
• Keyboard accessibility.
  
• Indicates the presence of sub-menus by automatically adding arrow images to relevant anchors.
• Drop shadows for capable browsers – degrades gracefully for Internet Explorer 6. Can disable shadows completely via options object.
• Can show the path to your current page while the menu is idle.
• Optional callback functions. The ‘this’ keyword within the handlers you attach will refer to the animated ul sub-menu.
