JavaScript tree / treegrid libraries

Question

I'm looking for a good JavaScript tree / treegrid package. Now -- before you answer:

It needs to be able to perform well with lots of nodes. Perhaps 1,000 sibling nodes. It needs to be able to draw to a usable state within 2 or 3 seconds with 1,000 nodes. It doesn't necessarily need to draw all 1,000 nodes at once -- if it supports some sort of "smart rendering" or fake scrolling.

Beyond that, column resizing, drag and drop, inline editing would all be nice, although I could probably add that functionality myself.

I've already tried dojo's tree and yahoo's YUI treeview. Both are too slow.

Answer 1

To be honest, I'm not sure you need a tree for your purposes. What I would recommend is you take a look at Steve Dekorte's vertex.js for your purposes. I can tell you that it scales extremely well.

Answer 2

Answering my own question here for others:

Here's one that I've found, which isn't free (except for GPL), but seems reasonably priced:
