Global menu in iframe

Hello, I need some help with a iframe Global menu,
on my site, I have a top menu to the navigation of the site , with links to other addresses, a “global menu”, and I’m making this a responsive menu, but when my site is mobile version, the “global menu” is up under the site . I wonder some quick way to make this menu get over my site, as was a responsive menu.

my site http://www.probeleza.com.br

thank you for the help, sorry for my english !
