I'm looking for a fold out menu that has at least four submenus under the main one.
I was using the one at dynamic drive but you can't really customize it like you can with the one at dhtmlcentral. I don't know if you can add another submenu to the three already provided with the code at dhtmlcentral or if there's a better one out there.
Any help would be greatly appreciated. Thanks.

Somebody was looking for a menu tree a while back, here are some -
