I know there’s a ton of great accordion plug-ins out there. I needed a really simple accordion so I rolled my own. Here’s a Simple and easy to use accordion.







		<title>jquery accordion - simple</title>

		<script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.min.js""></script>
		<script type=text/javascript>	
			$(document).ready(function() {
			//attach this function to ".accordion" class on click.
				//if the class is currently "closed" change to open and display div named #other-
					//console.log ("opening");
					$('#other-' + $(this).data('id')).slideDown();
				else {
					//console.log ("close");
					$('#other-' + $(this).data('id')).slideUp();
