I have applied changes to a problem I was having for UL dropdowns as suggested by Harbinger OTV and the ul is now centered but I'm still having a problem with the 2nd level dropdown. There appears to be 2 areas in it - on the left is the text of the li's (with text still wrapped) and on the right is an area with the background I used.

I've tried several combinations of the changes suggested but some just make it even worse.

All I need to finalise now is the dropdown items aligning to the left, not wrapping text with the background situated correctly.

Hope you can help me again.

see www.radycalheating.com/indexeng1.php for example prob.
relevant code is
Code:
#content {
	clear: left;
	color: #ccc;
}

#nav, #nav ul { /* all lists */
	padding: 0;
	margin: 0;
	list-style: none;
	line-height: 1;
	float: left;
	left: 50%;
	position: relative;
        
}

#nav a {
	display: block;
	width: 6.5em;
}

#nav li { /* all list items */
	width: 6.5em; /* width needed or else Opera goes nuts */
        float: left;
	left: -50%;
	position: relative;
	margin: 0 2px;

}

#nav li ul { /* second-level lists */
        overflow: visible;
	position: relative;
	background: #ffe4af;
        z-index: 2;
	width: 12em;
	float: left;     
	left: -999em; /* using left instead of display to hide menus because display: none isn't read by screen readers */
}

#nav li:hover ul, #nav li.sfhover ul { /* lists nested under hovered list items */
	left: auto;
}

#content {
	clear: left;
	color: #ccc;
}
