Issue when on mobile

Is it possible to disable the sticky menu on mobile devices, or smaller screens? On iphone 6 and similar sized devices, the sticky menu takes up too much room on the screen, 80% of it, and makes me unable to read the content? or if there is an option to make the menu smaller on smaller screens or something to resolve this.
