Can Colin push sold-out products to the bottom of a collection?

Yes. Colin can do that.

He can keep in-stock products higher in the collection and move sold-out products to the bottom without removing them from the collection.

Here’s how:

1. Open the collection in Collections.
2. Open Advanced sort and click Edit sort.
3. Check the box Push sold-out to bottom same day or after # days.
4. Click Save.
5. Click Sync to apply the new order.

Colin will keep sold-out products below the available ones whenever that Advanced Sort strategy runs.
