I see the option to link relationships in the sidebar that shows up in Gutenburg, but I need front end users to be able to link CPTs via relationships on the front end. Is that not an option? I've tried every setting in relationships and can't seem to make it work.
Each relationship box has the ID {$relationship_id}_relationships_from and {$relationship_id}_relationships_to. You can include these IDs in the form shortcode to show it on the front end.
Thanks. But I'm not understanding what the meta-box-id-1 field is a placeholder for? Is this the ID of my front end form? A field? I'm not sure what I should be using there.
