Add storefront filtering
Storefront filters allow you to set up product filtering on your search and collection pages. When you enable filtering, customers can filter your products by availability, product type, color, or other options to find the products that interest them the most.
Shopify Search & Discovery app
Customize the filters in your store with the Shopify Search & Discovery app. The app also allows you to customize search results and product recommendations to give you more control over how customers discover your products. Learn how to customize filters with the app.
Check if your theme supports filtering
To use filters, you need to have an Online Store 2.0 theme installed.
You can determine if your theme supports filtering by going to Online Store > Navigation in your Shopify admin. If your theme doesn't support filtering, then a message is displayed in the Collection and search filters section. You can still create filters for your store, but they aren't displayed in your online store unless your theme supports the feature.
Display filters
Themes that support filtering include a section setting that allows you to activate or deactivate filtering for your online store.
For Shopify-developed themes, this setting is located in the Product grid section of Collections pages, and in the Search results section of the Search page.
After the customer selects a filter option, the resulting list of filtered products will automatically update to display products that match the customer's criteria.
