Not sure whether you are talking about a filtered LIST or portals containing related files. Let's put it more clearly:
• I assume you have a field for Region, which has a dropdown list of regions
• Do you then have another field for Category, which has a dropdown list showing categories? Ditto for Specialty?
• Or do you have a portal to show Categories and a portal to show Specialties, that should show all the records relevant to the Region you select in the first field?
Yes, I have 3 separated Drop Down fields both in the Main Table and as Global fields.
I am attempting to use a single portal.
So initially, I'd like it to show ALL records in the Main Table in the portal. Then I could filter them down by Region, Category, Specialty, or any combination therein. And go backwards and go from a specific 3 filtered result to maybe 2 or 1 filters.
Example, if I had NY and LA by Region. And Category was year. And Speacialty was type of cars. I'd like to show all cars available. Be able to show just cars from 2015. Or just Hondas. Or, NY, 2014, Hondas. Or 2014 Hondas.
