Dynamic Windows Tree Menu

[Lytheum]

Does anyone know if there is a source/tutorial already written to generate a dynamic windows tree menu? (Example: http://www.phpguru.org/static/treemenu.html)

I tried tying opendir() in with the free source on that webpage but I had no luck.

Like I could designate a directory as a variable, and it will show everything in it, like this:

[quote]
-Main (Main Directory)
  -Sub (Folder within Main directory))
  ...File1  (File within the Sub folder)
  ...File2 (etc..)

[/quote]

Sorry if I'm not being clear or it doesn't belong here, my excuse is as always, it's late.
