filter by checkbox
Is it possible to have a field, which displays all types entered in the typefield as checkbox. Then I could check or uncheck the types and FM filters me, and only shows checked types.
Ex: I would have cars. FieldA shows me type (mustang, pickup, yaris, corolla) and Field B the brand (Ford, Toyota)
I need FieldC which should show me Ford, Toyota which a checkbox. If I check Ford, FM should show me only Ford cars.
How can this be done?
