Group Type dropdown allows the user to specify the type of the group that is being created. Only groups of type "Ad" can be added to a Campaign.
Group types are provided by FADEL, therefore users cannot create or delete specific group types. If a specific group type is thought needed, a support ticket should be logged requesting the addition of the new group type along with use case for its utilization. This allows the product management team to assess the system possibilities for the requested group type.
