I’m wondering if it’s possible to have headers made with GPP “Page Headers” addon appear ABOVE the navigation – just like you can show the regular header with site title, tagline etc above the navigation by default. I’ve tried “Merge with page header”, but that doesn’t work.
Decided not to use the method in the current project; but what you linked looks just the business. Will remember and search for this thread when the need arises. I’m pretty sure it’s solved, so marking as such.
