I have adjacent posts set up correctly but it’s displaying all of the posts/pages. I need it to show specific ones. The easiest way would be by parent URL if that’s possible as I need to do this multiple times. So www.example.com/sydney/ would be the URL and every page that uses the sydney parent would be displayed and nothing else.

Many thanks

Danny
