This is what I have tried to do several times, I think. I am in theme 2024.
I do: Apperance – Editor (Design) – Templates – Add template – Custom template – Named it “Engelsk sida”. Now comes a suggestion for a pattern, this suggestion looks exactly as the pattern I use for my regular Swedish pages. If I use this pattern and start to edit the menu in the header, all pages (including the Swedish ones) are changed. Is this where I go wrong?
Can I make a separate header with the same design as the Swedish?
