Show collection image
This option will pull the collection image, set in the Products > Collections area of your Shopify admin, and display it on your collection pages.
This option will pull a collection description onto your collection pages. This text content can be added in the collection admin (Products > Collections).
Enable tag filtering
The Enable tag filtering option allows visitors to sort products using custom tags (add these to the Products editor in the Shopify admin).
Specify the Rows and Products per row that display on your collection pages using the dropdown menus. These settings only apply to desktop view.
