Building a multilevel Navigation

[Texta]

Yes, I agree, thanks guy for the code. But someone needs (please) to pull this together.

Too me it's (at the moment) a bit unclear which code to use ans which modification to make AND how to call the nav-menu in the end.
For example, I just get "sublevel"-menu-entries for the top-pages and NOT the sub-pages. Very strange.

for example starting on the Top-Page1:

Code:

-Top-Page1
-Top-Page2
-Top-Page3
-Top-Page4

then changing to Top-Page2, I get a sub-menu, displaying top-pages 1to4 under top-page1:

Code:

-Top-Page1
       -Top-Page1
       -Top-Page2
       -Top-Page3
       -Top-Page4
-Top-Page2
-Top-Page3
-Top-Page4

When changing to a sub-page, just the top-pages get diplayed in the menu.

Still trying to figure it out (new to php), but would be nice if someone could put this together and give a short example. Thank you!
