The Content Relationship field is used to link to another document in your Prismic repository.
Configuration
Assign the Content Relationship field a Field name, API ID, and Field placeholder that will display in the entry editor.
Then set any constraints you need. The constraints will automatically add filters for Custom Types and/or Tags when an author is selecting a document.
