There's nothing like that that I've seen yet. I would think it would be pretty straightforward to create a set of containers with overflow:auto, load the first with data, then load each successive one asynchronously based on the item clicked in the previous container. If you get a working example, please post it for others!
I am just now learning this API. I am impressed. It'll probably be a while before I figure this out. It would need to act like the column view in Mac OS X. Click on a folder and you get a new one on the right. if you click the left pane it kills the right and creates a new one with the directory. I have a way to go. I'll be watching for something like this.
