Not sure if this is a bug report or rather a suggestion...
1. Dragging a TLI to a different grid will remove it from the original grid / position (removes the field value). To retain the original field value, I have to hold down CTRL during the drop (adds field value of second grid). This happens regardless of whether the item is dropped as a TLI or a child item in the target grid.
>> This is as I would expect.
2. Dragging a child item to be a TLI in a different grid can have two different effects:
A. If it was assigned to the field represented by the original grid, it will be 1. removed from its parent, and 2. lose the field value for the original grid.
>> I'm not quite sure this makes sense. Maybe it should then re-appear as a TLI in the original grid as well or the user should be prompted by a dialog?
B.
