I have a tree-like datastructure of some six levels deep, that I would like to represent on a single webpage (can be tabs, trees; ....)

In each level both childnodes and content are possible. Presenting it like a real tree would be not very usable (too big).

I was thinking in the lines of hiding parts of the tree when you drill down and presenting a breadcrumbs or the like to keep you informed as to where you are...

I guess my question boils down to : any ideas / examples ?

Tx!
