I hae a web site that I am designing a menu system for. I am utalising a CSS/Javascript/HTML menu that I have used on many occasions.

The menu is horizontal and uses nested unordered lists to drive it.

Included is a complete test page (work in progress and strictly a test set!)

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<style type="text/css">

.menumain {
	background-color: #156ab9;
	float: left;
	width: 984px;
	margin: 10px 0px 0px 0px;
}
ul.menu {list-style:none; margin:0; padding:0;
}
ul.menu * {margin:0; padding:0}
ul.menu a {display:block; color:#fff; text-decoration:none}
ul.menu li {position:relative; float:left;}
ul.menu ul {clear:both; position:absolute; top:35px;  left:0px; background:#156ab9;display:none; opacity:0; list-style:none; width:540px;}
ul.menu ul li {position:relative; width:280px; margin:20px 10px 20px 10px;}
ul.menu ul li a {display:block; padding:5px 7px 5px 10px; background-color: #eeeeee;color: #FFFFFF;}
ul.menu ul li a:hover {background-color: #125ca0;}
ul.menu .menulink {padding:10px 5px 10px 10px; font-weight:bold; font-size: 14px;}
ul.menu .menulink:hover, ul.menu .menuhover {background-color: #125ca0;color: #FFFFFF;}

What I would like to achieve is to have the 'popup' menus appear left justified to the 'mainmenu' <div> rather than relative to their immediate <li> parent.
