<h1>Example: Move nodes using drag-and-drop</h1>
<p class="description">
This sample uses Dynatree's built-in drag-and-drop feature to move nodes.<br>
- autoExpandMS option is used to expand nodes on mouse hover.<br>
- The container style uses `overflow: scroll` to demonstrate auto-scrolling.<br>
- When dropped, the node is moved to the target.
