- Content type groups | drupal.org
Content type groups was designed to handle the use case when you need to populate select boxes or other interface elements with certain content types but not others. This module allows you to create an unlimited number of groups of content types through the UI. Once a group is created, it can be referenced in code using API functions and in Views.
