Hi there and thanks for a fantastic mod! I've modified the menu quite heavily, but found no way of creating a "tree". What I basically want to do is...

Code:
Menu header 1
  |_ Submenu A
     |_ Item A
     |_ Item B
     |_ Item C
  |_Submenu B
  |_Submenu C
  |_Submenu D
     |_ Item A
     |_ Item B
     |_ Item C
How do I create the tree branches for Item A-B-C? This has nothing to do with categories, as I've already removed them, but with ordinary menu items. Categories seems to rely on ul_generator, I want to go way more simple and hard code it in there.
