how to create a new tree from a existing tree node by draggi

Hi,

I have a page with two frames. One frame loads a tree and another one is empty.

How can I create a new tree in a empty frame by dragging and dropping a node from a existing tree in another frame?

Thanks

You need to have an empty tree, with enabled d-n-d, initialized in second frame.
By default tree allows drop on empty tree space - so you will be able to drag item from first frame and drop it on the empty tree in second frame.
