Hello.
Change the custom field, and add more custom field type...
I think osclass custom fields can be very usefull to create real estate but specially avertising sites for cars, specially for cars where exist allot of car makes, and allot of car models for each make, if i take in account only the cars, trucks and motorcycle, makes and models, this a huge ammouth of custom fields...
Should exist a better a way to create dedicated real state and cars sites...
Forget the free real estate and cars attributes, they are very imited if want to and more options and very outdated.
I can use multilanguage attributes plugin, but i dont know if will support a huge amounth of data.
Best regards
