    :name: group-allowed
    :Path: $GLOBALS['TCA'][$table]['columns'][$field]['config']
    :type: string (list)
    :Scope: Proc. / Display

    A comma list of tables from :php:`$GLOBALS['TCA']`, for example "pages,be\_users".

    ..  note::
        If the field is the foreign side of a bidirectional MM relation, only the first table is used and that
        must be the table of the records on the native side of the relation.

    ..  note::
        When using Extbase, you also need to fill
        :ref:`foreign_table <columns-group-properties-foreign-table>`
        property with the same table name as used in
        :ref:`allowed <columns-group-properties-allowed>` property
        (but with just one table name).

Group relation to be_groups and be_users
