Drag and drop the files or folders
from the list on the right to treeview
to move it to that folder.

Also hold CTRL while dragging to copy instead of moving.


This example was created using an aditional script file, that does all the work behind the scenes, loaded using:
<script language="javascript" src="dndToFolder/dndToTree.js"></script>

Each of the dragable items was given a unique id (dragItem1, dragItem2, ...etc) and were made dragable using:
<script language="javascript">
  ob_attachDragAndDrop(document.getElementById("dragItem1"));
  ob_attachDragAndDrop(document.getElementById("dragItem2"));
  ob_attachDragAndDrop(document.getElementById("dragItem3"));
  ob_attachDragAndDrop(document.getElementById("dragItem4"));
</script>

When drop is made in one of the treeview's folders, an action can be taken depending on whether it was a copy or a move. Currently if there was a move, the draged item is removed from page while if there was a copy, nothing happens. The behavior can be easily changed by modifying the dndToTree.js script file and changing the content of the functions ob_dnd_handleCopy and ob_dnd_handleMove.

With minor modifications, this script can be used to drag any type of element to any treeview.
