By default, Shopify will display products on a Collection page by "best selling," However, you can change this default order by reorganizing your products manually or choosing an alternate sorting option within the Collection's admin page by following these steps:
Step 1: From your Shopify Admin, navigate to Products > Collections.
Step 2: Select the Collection you want to modify.
Step 3: Scroll down to the "Products" area where you will see the "Sort" drop-down.
Step 4: Here, you can change the selection to another option! You can choose from:
- Product title A-Z
- Product title Z-A
- Highest price
- Lowest price
- Newest
- Oldest
- Manually
- Best selling
Step 5: If you choose "Manually," you will be able to re-order the products in this area by dragging and dropping them in your desired order:
Please note that changing the sort order only applies to the given collection. If you want to change the order of other Collections, you will need to repeat this process.
