    <h1>Selectable and Draggable</h1>
    <p>
      This demo demonstrates how to create selectable items and make them draggable. In this way you can drag single items, or select many of them and drag them as a whole. You can either doubleclick the items or use box-selection. Then drag the selected items around the screen. Use <tt>right click > view source</tt> to see the underlying Javascript code.
