Feature request: top bar nav

[markc]

Any hints as to how I could add a typical bootstrap-like top bar nav that collapses in mobile view with a RHS hamburger icon?

I really like the one create here - https://www.adam-bray.com/2017/02/18/create-a-html-5-and-css-3-mobile-navigation-bar/
Very simple, sleek, good cross-browser compatibility, nice css animation.
