	Panels
	Mark Simon, Comparity Training

	Feel Free to use

	This script creates displays and manages tabbed panels.
	To use:

	1.	Copy the panels.js and panels.css files somewhere

	2.	Head Section:

		<script type="text/javascript" src="includes/panels.js"></script>

		<script type="text/javascript">
			window.onload=function() {
				new panels('panels');
			}
		</script>

	3. 	Create the following hierarchical structure:

		<div id="panels">
			<div title="...">
				...
			</div>
			<div title="...">
				...
			</div>
			<div title="...">
				...
			</div>
			<div title="...">
				...
			</div>
			<div title="...">
				...
			</div>
		</div>

		That is:

		(a)	You have a div called "panels"
		(b)	The div contains a set of divs.
			Each div may contain other divs, which will not appear as tabs.
		(c)	Each div has a title="..." attribute.

	The id of your list above defaults to "panels".

	Disclaimer:

	This script probably works and it does what it does.
	What it doesn’t do it doesn’t do. E & OE
