hi
I have one panel whose layout is border layout and in the center of this panel, there is a portal. Also, there is a tree in the west region of the panel.
I want add new portlet to the portal by dragging one node from tree and dropping it to the portal.
You need to use the Ext.tree.plugin.TreeViewDragDrop to easily get the tree to be D&D. Then the portal you need to create a drop zone with the same ddGroup.
