Im new at this so get ready. I have some dropdowns in my catalog. Sunglasses, women's wallets, men's wallets etc. I have products I downloaded to my shopify but I can't pick and separate them into their individual dropdowns. It only lets me do all products. Or I'm doing something wrong. So in my sunglasses dropdown I have sunglasses and wallets. You know what I mean?
Karlie here from the Shopify Guru Team! What you would want to do is separate your products by collection using this guide! After creating your different collections, you can then set up your dropdown menus using those collections - this doc will go through the steps needed to create your dropdown menus!
I hope this helps, but if you have any further questions - be sure to reach out to Shopify support!
