Content Relations

Content Relations lets you link a post to any other post. Relations are typed - you name the kind of relation ("see also", "part of", whatever fits) - and ordered by dragging. In the block editor, a Content Relations panel in the document sidebar edits a post's relations the same way you'd edit categories: grouped by type, saved with the rest of the post, no separate save button. The classic editor keeps the same editor in a meta box instead. A Related content block - a variation of the core Query Loop block - lists a post's own related posts under one relation type, in the order you set in the sidebar, meta box, or the Tools screen. Drop it in wherever a "related articles" section belongs; it uses the same layout options as any other Query Loop. Tools → Content Relations lists every relation type in a sortable, searchable table. Opening a type there lets you reorder or remove its relations across every post that uses it, grouped by source post, with drag handles or up/down buttons. Each related post's relations are exposed on the REST API under a content_relations field, so a headless front end can read them too. Relations to unpublished posts are hidden from anyone who cannot edit posts. A WP_Query extension lets a query filter by relation: give it a related post id and, optionally, a relation type, and it returns the posts related to it.
