Relation Input

Enables to reference items through a WP-JSON endpoint.

  }
}

WARNING

Post types and taxonomies must be exposed in the REST API to be available in the relation input. Read this cookbook recipe to learn how.

TIP

If you want to reference posts or terms, you probably want to use the post and term input types instead.
