I've done exactly as you propose. Wrote my own tree viewing library though. It's not very hard to do, each element has a "thing" for the actual item, and then another "thing" for child items. At they're simplest, the "things" would just be DIVs, but you'll probably end up with a DIV containing two DIVs (for the item and children), and then an A for the item as well. But who knows.
You just set up some data structures that keep track of what items have undergone a child check, and if they haven't render an "expand me" icon. When clicked, it should request children from the server, and then render them into the "thing" for the item's children. That way you don't have to completely rerender every update. Also, I believe that FarCry has something like this in there. Not sure how it works, but I seem to recall a dynamically expanding tree. It's all free (as in speech and beer), so you could well hijack code from there, and maybe get both pieces (the DHTML and the JS Remoting) and have them already integrated as well. cheers, barneyb On 6/19/05, James Holmes <[EMAIL PROTECTED]> wrote: > OK, I've been investigating this for a while and the major stumbling > block is finding a JS tree control that allows branches to be inserted > at runtime; everything I've found so far requires the whole tree to be > defined in some way before the actual tree content is generated. > > Does anyone know of a JS tree that has an API for inserting branches > at runtime (e.g. from a remoting request via AJAX)? > -- Barney Boisvert [EMAIL PROTECTED] 360.319.6145 http://www.barneyb.com/ Got Gmail?
