Prevent Drop as Append for Tree

[leela]

Hi,

I have 2 questions.

 

• I have 2 trees, The user should be able to drag and drop the elements from the left tree to the right tree.
   Initially the left tree would be empty. When it is empty, I am not able to drag and drop any elements on to it.
   What is the best way to achieve this?
  
• Also I want to prevent dropping of nodes with 'append' point value for few nodes.
  Is there a way I can change the 'point' value from 'append' to 'top', before the drop happens?
  

Thanks,
Leela.
