I was trying to use the panelbar component as described in this post. I actually switched to the treeview in the end, it was just easier. I've got it working now, but at the moment it's quite cumbersome having to modify the underlying data set, fiddling with template selectors etc, just to achieve something as simple as an "Add node here" button. It would be great if this functionality was built into the treeview. And while I'm at it I might as well request node editing as well. /Henrik
