Hi Jeremy!
Also NL of BE ? ;-)
Anyhow. Great help!
I implemented your code. But I faced another problem:
Because of $ajax->submit() my dhtmlTree isn't draggable anymore. It's
just printed out link the HTML tree.
If I push the "save" button it does nothing (maybe because of the
dhtmlTree problem).
Maybe you had this problem too?
Thanks in advance!
Grtz,
Tim
