I need to limit the max depth a user can drag and drop a node.

For eg. Taking root level as level 1, i want to limit user to only drop till the 3rd level, in other words, only a tree of 3 levels is allowed.

I tried to change the node values onDropEvent, but it will create a duplicate with the changed valued and end up causing alot of errors due to duplicate keys.

Kindly advise, thanks!

You can use the addFolderDropHandler method to add a handler to handle record drops. After that you can use FolderDropEvent.getFolder() to get the target folder for the drag-and-drop operation to check your precondition and cancel the event if your condition is not met...
