e4x XML with Tree, definitely. Here is a link to a sample app that uses a tree and some other controls to edit an xml file. It doesn't add children on node click, but it does allow you to add nodes. Maybe some of the techniques will help.

What is everybody's thoughts on that? -Kyle On Dec 20, 2006, at 1:19 AM, Lachlan Cotter wrote: Hi Kyle, Listen on your tree control for the itemOpen event. Retrieve the tree node from the event, pull from it what information you need for your next query. When the query returns, append the results as children of that node. Bindings should update the tree control. Is that what you were looking for?

So here I am. The application I am designing needs to display a hierarchal list of codes. All the codes are related to each other in that one is abover another. ... Inside my database there is a table that raggedly displays this data in 11 columns (the 11 levels) 1 2 3 4 5 6 7 8 9 10 11 AA AAA AA AAB AABA AA AAB AABB AA AAB AABC AABCA AA AAB AABC AABCB etc So I want to query this data in which case I have already built a function in ColdFusion to return the DISTINCT items for a level that I specify Which in my example would produce AA AB for level 1 I am able to return that much to a tree and have it display the folders by adding a column pragmatically to the Query called "children". There are 10s of thousands of records in this table so I do not want to grab all this data at once. I want the next level for a specified entity to be pulled from the CFC when I click it. How do I append this information to a folder item? Thanks a bunch! -Kyle
