Footer

Hello. I can't create footer with your theme style. In theme options, in footer menu I haven't template styles(screen in attachment). I try create it like in your guide, but I haven't visual composer in header/footer wordpress menu(screen in attachment). Then I try to create it with visual composer on page, it appear at the top of my site. If i create standrat footer, i cant customize it, but it appear at the bottom of my site. How I can tune my footer with your theme styles and locate it at the bottom?
