Scope

Default

db

Configures the internal type of the group type of the element. There are two possible options to choose from:

folder
This will create a field where folders can be attached to the record.
db
This will create a field where database records can be attached as references. As it is the default it can be omitted.

Deprecated since version 9.5

The internal types file and file_reference have been deprecated with TYPO3 9 and removed with TYPO3 10. Extensions that used group fields with these internal types should switch to use FAL references based on type=inline instead.
