Tree Drag and Drop Functionality

• label1 | |*label2 |*label3 |___label4 |___label5

I want a tree in this structure, having line between the nodes, also, instead of Open and Close Folders, I have added my own graphic there with label. I did by extending TreeItemRenderer Class. Now, I if iam dragging and dropping a child node ex:label5, and try i drop it above label1 here, it is getting dropped there. i.e.,it is becoming like
