I have many small VBox inside a big VBox. Each small VBox contains Buttons, Text, and TextArea. I want to be able to drag and drop the small VBox to change the order displayed in the outer big VBox. I can drag the small VBox around using DragManager, but the big VBox does not allow me to drop
the small VBox in a different location. How to make the outer big VBox drop enabled? Any suggestions?
