multiple layers on anylinkmenu?

[utopia]

I made a menu based on http://www.dynamicdrive.com/dynamicindex1/dropmenuindex.htm

There's one problem that I want to solve. Is this menu capable of having multiple layers? The most relevant example that I found on the web is www.wowhead.com It has multiple layers of menus. If the anylinkmenu is capable of doing that, can anyone tell me how to do it?

Thanks
