Overlapping dropdown menubar

I see it is working fine now. I would suggest however to keep the menu in one line, looks nicer. If you need all the first level menu items, you can decrease the font size of the menu.

In style.css file look for

.sf-menu a {
	padding: 7px 15px;
	text-decoration: none;
	zoom: 1; /* IE7 */
	font-size: 16px;
	font-family: 'Arvo', arial, helvetica, sans-serif;
	text-transform: uppercase;
	color: #000;
	font-weight: 400;
}

just change the font-size.
