Add conditions in form filtering

[perfect]

My table has 3 fields:

• One field is country selection - e.g. USA, EU, Canada..
• One field is product - e.g. table, chair, cabinet...
• One field is supplier - e.g. supplier A, supplier B, supplier C. 

Does anyone know how to set rules/conditions in SAME field of airtable FORM INTERFACE at below scenarios? 

• Scenario 1 - select USA and table, filtered option is supplier A
• Scenario 2 - select EU and table, filtered options are supplier B and supplier C 

I am not familiar "add condition" or "add condition group" in form filtering. Pls. advise if you know how to do it. 

Thank you.

That is not yet available in Airtable, but it is coming soon. For now, you can only get that functionality with Fillout’s advanced forms for Airtable, which offers over 100 advanced form features that aren’t yet available in Airtable.
