[Plugin: Mobile Smart] custom theme

Hello–This is off topic but I have a custom theme managed by media queries for the mobile theme. But I am having problems with my drop down menu. I am previewing it in device central in DW but the drop down looks terrible and you basically can’t access it even though you can see it. I am using drop down menu widget. Can you suggest a fix for this? Everything works fine on the desktop version. Thanks, Susan
