<p>This example shows the use of the drag shim when dragging nodes over other troublesome nodes.</p>

<style>
#demo {
height: 100px;
width: 100px;
border: 1px solid black;
cursor: move;
float: right;

<p>Try dragging the proxy element over the iframe below, in most browsers this will not happen. Now click the <code>Turn Shim On</code> button and drag again. Now you can drag over the iframe.</p>
<p>You can see the shim by clicking the <code>Turn Debugging On</code> button while using the shim, the default for this example is that the shim is off.</p>
<p><button id="shim" value="off">Turn Shim On</button> <button id="debugShim" value="off" disabled>Turn Debugging On</button></p>
