DHTML Script - TopMenu		[View Sample]

A great sliding menu script where you just set a few variables and makes the content for the menu and it does the rest. Also added in this script is a feature that makes the menu will follow you down when you scroll the page. This script can now be used as single or multiply topmenus.


Insert into <HEAD>
