Menu collapses when page is vertically resized

Hi all,
thanks for developing such a nice tool!
Unfortunately, now I need the menu to be resized/collapsed in its button form when the page is resized in its height, and not just in the width.

The website we are talking about is https://www.jacquesdurand.com
As you see, if you resize the page vertically, the menu goes under the logo, and above the page.
I wanna find a breakpoint before it touches the logo and that transforms it into the classic menu button.

How would I achieve such a thing?

Thanks in advance!
