title: Changing a node's site in ALV tree
body: <p>I have an ALV tree and basically what I need to do is to slide (drag) a specific node to the top or bottom or a specific location in the ALV tree.</p>
  
  <p>How could this be accomplished? </p>
  
  <p>For example, here I would like to slide the <strong>IF</strong> node in place before the <strong>AFFECTATIONS</strong> node:
