Dropdown menu on X-Cart.com - is it fancy categories?
 

what is the script that x-cart uses on their website for the drop down menus? is it the same as fancy categories or does anyone know how i could implement something like it?

Lots of menu scripts in Custom Mods.

Or you could try any of the Dhtml script sites.
