I have pages that list different post types (post, media attachment, page, custom post) created via the relationship field. These index pages acts as a parent of the posts in their relationship field. My question is: Would it be possible to create a next/previous pager on the ‘child’ post types so I can navigate back and forth without having to return to the index page?
My index page could list ‘Item 1’, ‘Item 2’, ‘Item 3’ in a relationship field.
Then on the ‘Item 2’ post I would have a ‘Previous’ link that links to ‘Item 1’ and a ‘Next’ link that links to ‘Item 3’.
Is that possible? Can someone steer me in the right direction?
