GUI question : representing large tree on a webpage

I have a t开发者_如何学编程ree-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 breadcrumbs or the like to keep you informed as to where you are...

I guess my question boils down to : any ideas? Or example websites of course?

(the question is just about the view, not about the technology, but for the record, I probably use jquery)

Tx!

I would think a grouped outline would be best where you could simply expand and collapse each group (node) at will. Think standard outline where parent nodes are larger headings than child nodes.

how i do myself is define a max-height on all tree ul, when some tree node are highter the scrollbars become cumulatives, just style bars to hide them
