Links

Relationship

Relationship and post_object fields store IDs of selected posts.
In the Basic version, if you add these fields to your View they will be displayed as links. For example you could use the field to link to another post or to create a read more link.
Sometimes, instead of displaying the selected post as a link, you may need to display some fields of the selected post with your current View. With the Pro version, you can do this.
