Mobile tabs (secondary mobile menu)

Hi,

I love GeneratePress (highly functional, lightweight and well documented).

I have 99% of users on mobile devices, so I’m looking for a secondary top mobile menu. By that I mean adding an additional row with 1-5 text links below the current mobile menu element.

Is there an option how to do that in the premium version of the plugin? If yes, do you have an example?

I can hire someone to develop this, but I prefer to have it in the theme itself to ensure future stability.

Thanks in advance
