First off I just want to say how awesome your Smartmenu is – it’s clean, sexy and super easy to implement! (And I’ve tried several)
The only issue is the submenu background color does not show in Internet Explorer 10 (my nemesis).
I have a feeling I need to add something to the CSS code. At first the main background of the menu was not showing either until I inserted position:relative;. This fix did not work for the submenu though.
