OK, getting context menus and popup content sensitive information is great... but how do you make it pretty easy? Well, I don't know about you but this seems pretty easy to me! We are putting this into our test queue and looking at making another ICE element with it.
<ul id="mymenu">
<li>test 1</li>
<ul>
<li>test 1.1</li>
<li>test 1.2</li>
</ul>
</ul>
<div></div>
<script>
$("div").contextMenu("#mymenu");
</script>
