This is definitely possible with both tree components. There are two tree components: tree and tree2. I worked on tree2 which supports client-side toggle in addition to server-side toggle. You're talking about server-side toggle (you'll want to process the expand action on the server using actionListener instead of on the client-side using javascript.)
First order of business: you should check out the latest examples in the simple examples webapp. You can get the source in CVS or get the binaries from nightly builds. The latest source/nighlties have new tree2 examples that are not in 1.0.9m9. There are no examples showing the dynamic addition of data but it would be relatively easy to come up with one. Perhaps I will add one at some point. There's enough there that you should be able to figure it out though. Feel free to contribute an example yourself if you come up with one. sean On 4/28/05, Jeffrey Goodwin <[EMAIL PROTECTED]> wrote: > Hi, > > I am working on a project in which I need to dynamically create a large tree > with a large number of child nodes/levels.
