Hello anybody who takes the time to read this!

I am not new to CFM but have not hit it to deep as of this point. Here is my problem and I hope I can explain this well enough.

I have a page that will be driven left to right based on a parent/child relationship. The problem I have is figuring out how to loop indefinitely since my record set could contain a parent with a single child with no children or it could go 100 levels deep. So in reality, I basically want to make a tree like view that starts with 2 parents (USA and CANADA). Now "I" know that those both have children in my data structure (The query returns ID,ParentID and NAME. When I click on USA I need to see all 50 states in a new table cell to the right of it. Then when I click on a state, I need to see all of it's counties... then when I click on a county I need to see all of it's children which could be cities, agencies, city governmets etc...

All of these clicks I speak of will be post backs and no javascript or hidden divs since I need to make this little app accessible for the blind.

Also, if I have USA exapanded m-levels deep I need to be able to close it at any of the nodes. I also need to be able to click on CANADA and keep all the USA nodes open. So I need to figure out a way to track what's open and how it's connected etc so that I can export out the diagram in a PDF.

PLEASE HELP!!!!
