Developy a Management tree in Php

Hi, I have a huge problem !!! I try develop a managementtree (like W2K Management) for my Network management Tool. My 1. Problem: This Tree should be changeable about a web interface. -> thats no the real problem. My 1. Problem: How I can develop this tree - I haven't any Idea. How I can do that: if the user click on a directory the subdirectory or the files are show. I thought I can do this with parametes but if my tree have 100 entries its to mutch. My secound think I use a developed Java-Script Tree -> but I cann't manage this well. Any Ideas. Thonix -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net
