Collections now support multi-source and variants

This release expands collection capabilities to help merchants run complex merchandising strategies without workarounds such as duplicate lists or third-party apps. Previously, collections were created only by automated conditions or hand-picked products.

You can now build a collection from multiple sources, target specific variants, reuse other collections, and more. Highlights include:

• Multiple sources in one collection. Combine automated conditions, hand-picked products, exclusions, other collections, and sources from apps in a single collection.

• Variant-level collections. Build collections around specific variants, such as a size or color. Those variants appear on collection pages, in filters, and in supported sales channels, including Online Store and POS.

• *Collections as building blocks. *Add a collection as a source inside another, so parent collections stay in sync when source collections change.

• ** Reuse across your business. **Apply the same collection in supported workflows such as discounts and taxes, including variant-level collections.

• ** Redesigned collections admin UI:** Use a visual grid for drag-to-reorder and bulk moves, list view for detail, and control over the sort order customers see on the collection page.

• Sidekick support. Build and update collections with Sidekick on admin and mobile.

There are no breaking changes for existing collections.

• Existing collections continue to work and are updated in the new admin experience automatically. You do not need to delete or recreate them.

• If your store uses third-party or custom apps that interact with collections, ask your developers to update to API version 2026-07 to support these new capabilities. See developer instructions.
