Which menu are you talking about? What sub menu? Where is it suppose to display?
Please give a more complete and detailed description of the problem.
You can only edit the CSS? You have no access to the header.php?

Hi, if you view that page in Firefox/Chrome/IE9 etc you will see an orange sub menu. This is actually contained within the main menu at the top of the page, but moved out of it via absolutely positioning it.
I have no access to the Wordpress root inc files and can only edit the CSS.
