Menu drop down being blocked

Hi guys,

This plug in is great! However I have one issue after placing my google adsense header banner, the menu on the mobile version is being partially blocked by it so people can’t see. Is there a way to push down the menu or make the menu always show on the top of all the layers?

Thanks a lot!
