title: Grid Drag & Drop: Suppress for some records (groups)
body: <p>Hy there,</p>
  <p>is it possible to control which records can be dragged and where they can be dropped (suppress drag-operation either right from the beginning or in the middle during hovering)?</p>
  <p>What i need in detail is the following:</p>
  <p>I'm having a grid with some groups (lets say male &amp; female) and only want to activate the d&amp;d inside group 'female' which means 2 things:</p>
  <p>1.) I started dragging a record from group 'female' (Lisa). As soon as the drag is outside the group 'female' (above group 'male'...) it should display an error-state like when dragging outside the bounds of the grid:<br>

  <p>2.) Starting to drag an item from group 'male' should either not be possible at all (just don't show the d&amp;d panel) or show the error-state like mentioned above right from the beginning and never change to &quot;correct&quot;-state.</p>
  <p>Thanks,</p>
  <p>mike</p>
