Adding field groups to a field layout
Add a field group to a field layout to group and identify related fields with a descriptive label. For example, you may want all required fields in a group named Required Fields.
All custom fields and some system fields can be added to field groups. For a list of system fields that can be added to field groups, see System fields for use in field groups in field layouts.
