After the viewready event of the tree you'll need to set an onBeforeDrag method on the dragdrop plugin's dragZone like in the example below. You'll get the record using the event passed to the onBeforeDrag event and using the record's isLeaf() method determine if you'll return true or false in the onBeforeDrag.
