Help with Brooklyn theme header

Hi, I am using the Brooklyn theme and the menu is on the left side. I would like for it to be on top. How can I do this?

Much appreciated!

Found an easy fix. Reduced the number of menu items to 3. That did the trick. To add a 4th menu item, went into the theme scss code and reduced the font size from 14 to 10.
