I am newbie to airtable and scripting

We have a table to store our product inventory and associated photos.

I am trying to write a script to download photos selectively based on user criteria.

User will select a Item (Saree, Bottle), then he will select a brand (Karishma, Jonam) then he will select a catalog.

Based on these selections, we want to download all photos.

I have a schema product with

Item Name
Brand Name
Category Name &
Other Fields

unfortunately not getting a clear idea how to use group and filtering together to achieve this.

Looking forward to expert help
