Custom secondary menu

Hello!

Thanks a bunch for the marvelous theme you’ve created! It has helped my page be a million times more beautiful and responsive.

I’ve been building my page from scratch and now, after some time, I have encountered a problem. I wanted to first add a sticky sidebar to a page and, although I was successful with a widget (Q2W3), it didn’t look the prettiest. Then, I thought it would be best to have the custom menu as a secondary menu in that page only.

The problem is that it is displayed across all of my pages… is there a way I can have that custom secondary menu only on that page? Or if it would be possible to create another header, sidebar (or anything) that can “stick” to the page as you scroll?
