Doubts on Marinelli Menu I'm trying to have submenus like the ones that can be seen on http://marinelli.netsons.org in Cameras menu item. 

Could anyone point me on how can I achieve that? I don't know how to create the sections that can be seen in that submenu.
Megamenu might be of use.


  Mega menus are a type of menu drop-down, which seeks to overcome some of the usability drawbacks to traditional style drop-downs. Primarily, mega menus have two advantages:
  
  
  The information architecture of your navigation is made clearer and is visible all at once
  The amount of clicking, searching, and navigating is reduced
