Hi, What I am looking for i a graphic interface tor editing a tree data structutre. Example: let say i have a two column table of numbers. those numbers are structured i a clasic parent child relationship:

parent child

2  5
2  7
2  8
5  6
5  9
6  10
7  11 
7 1
...
[download]

now it is easy to make a simple recursive algotihm to traverse this tree but what i am looking for is a way to display this tree. it dousn't have to be perfect but it needs to be simple enough so that it can be used in a web app and it needs to allow editing. for example let say i want to move child node 1 from 7 to 2 then i would like to click on 1 and drag it to 2. is there any module that can do something like that ?? emphysis is on a drag and drop interface.

thnx

baxy
