Hi I'm a newbie with dynatree, but happy that i've found this supercool plugin. On the dynatree site, I've found an example how to use it with IFrames http://wwwendt.de/tech/dynatree/doc/sample-iframe.html I was able to adapt the IFrame example successfully. But i'm a bit stuck here, because I'd like to load the tree either via UL/LI or better, with Jason/Ajax. my problem now is, that I dont understand how to provide ther url/links with LI or Jason, so that clicking an entry still opens the linked site in the iframe. Also don't know how I have to format parents/children/subchildren in Json.. Would anybody be so kind to give a sample with iframe and jason/ajax or iframe with ul/li? Thanks a lot :-) G
