(Using master frame pages with all layout grids except for content place holder between the header and footer areas.)

1.) Which menus go to a hamburger menu at the set "menu breakpoint"?

2.) If using a non-hamburger menu the master frame page should have the same break point setting as the menu?

3.) When using a hamburger type menu the master frame page does not need a break point set.

Thanks a lot!

From the built-in menus 'responsive menu' and 'mega menu'
But there are many responsive menu extensions:

The menus do not necessarily need the same breakpoint. Whatever works best your your layout.
