I plan to have 2 trees.  The left one will contain selected items and the right one will contain non selected items.  When I load the left (Selected items) I will not display them on the right.

What I am looking for is a way when I drag and drop Root|Parent1|Child2 (See FIG1) from the right to the left that I see Root|Parent1|Child2 (See FIG2) on the left leaving FIG3 on the right.

The tricky part comes if I remove    Root|Parent1|Child2 and drop it back on the right.  No matter where I drop it I want it to go back to its original location like FIG1. 

FIG1

Root

            Parent1

                        Child1

                        Child2

                        Child3

FIG2

Root

            Parent1

                        Child2

FIG3

Root

            Parent1

                        Child1

                        Child3

There is no native support for such complex "drag back on place" functionality. The node can be set to any position (by moveItem feature) but tree can't locate a place from where item was dragged in one of previous operations.
