Region list display in composite field order?
I created a composite field to join field 'make' and 'model' together thinking I could then use the composite field to order the list by, however the composite field doesn't show as a field to select in the 'order by' list. Is this a bug?
I want the list to be ordered as follows (where Audi, BMW etc are the make fields and A1, A3, 1 Series are the model fields):
- Audi A1
- Audi A3 Sportback
- BMW 1 Series
