We are trying to populate a MB HTML field with some static data about related posts. We have the callback function working fine, as I am able to return the main post's ID in the field. However, upon attempting to use the methods described in the docs, I am unable to return any related posts. I am assuming this is because the MB API only works on the frontend, so I am wondering how the Connected To: section works in the post editor.
All i really need to do is return the list of related posts with a link to each one. If you could help me get the relationship, I think I can handle the rest.
