Thanks so much for your post. I don’t see the same thing on my end - there isn’t a burger or the option for that format in my header layouts. I’m using 7.1, if that makes a difference?
My header layout is set to exactly the one you suggested, but with links instead of a burger. But every burger nav code I find automatically aligns right and sometimes moves the logo slightly left. Looking for a code to override that, and fix the open menu issue.
