Um. I have thousands of posts with maps, it’s a regional destination vacation site. I NEED HELP. How is it even possible that this is not a functional part of maps? THEY’RE MAPS. This is the reason maps exist.
Sorry - you shared the screenshot of URL field type field namely "website":
=> hidden link
I do not understand, now you are talking about maps. Can you please share your problem in detail? Where exactly you want to display/add the "rel" attribute to URL field - on frontend correct?
