Selecting Related Content Items in the Sitefinity Module Builder

The Sitefinity Module builder allows you to create custom types on the fly for use as custom modules. In the 5.0 release back in February, a two new field types were added to the module builder: Guid and Array of Guids. These allow you to “link” content items using their Id properties, adding support of one-to-many and many-to-many relationships between your content.
