How to create a two-line responsive menu?

Question

css

Good afternoon, I started to study bootstrap, I hung up on the moment with the menu, the typical menu that is in the offsite tutorials is understandable, but I wanted to make another menu (in the attached picture)

The menu itself is in a container that is held in the center (do not pay attention to colors, different used, so that it would not be much clearer)

Answer 1

well, put another navbar under the other and all that's the problem is, if you need to color it in some other way - give extra. a class that distinguishes it from the main one.
