Reply To: Add custom fields to resources edit page

In the there’s a addon for the search form to give resources attributes and search for them. It was made for a customer, isn’t fleshed out and I’m not supporting it further. But as I heard from other customers it still works and should be enough for a simple select.
Add attribute in main settings, set its values in all resources and add it to the search bar with [attr title] if I remember correctly.
