Shopify Collections Are Changing: What Merchants Need to Know in 2026

The short version: Shopify is overhauling how collections work in 2026. The rigid "smart vs custom" split is being replaced by a flexible Collection Sources model — one collection can now combine automated rules, manual picks, exclusions, other collections, and app sources. Add variant-level targeting and native AI merchandising, and collections just became far more powerful. Your existing collections keep working, but what's possible has changed.

We build and merchandise Shopify stores, so here's the practical breakdown of what changed and what to do about it.

The old way: smart vs. custom (and why it was limiting)

For years, a Shopify collection was one of two rigid types:

• Smart (automated) — products added by conditions (tag, type, price, etc.).
• Custom (manual) — products added by hand, one at a time.

And you had to pick one. Want an automated collection but hand-remove three products that shouldn't be in it? You couldn't — you either fought the conditions or rebuilt it manually. Want a mostly-manual collection that also auto-includes anything tagged "new"? Not without workarounds. That either/or model quietly forced a lot of clunky merchandising.

The new model: Collection Sources (2026-07)

That split is gone. In the new model, collections are no longer limited to smart or custom. Instead, a "source" is anything that adds products or variants to a collection, and a collection can combine multiple sources:

• Automated conditions (the old "smart" behavior)
• Manual selections (the old "custom" behavior)
• Exclusions — explicitly remove specific products or collections
• References to other collections — build on top of existing collections
• Shareable app-owned sources — sources authored by apps

The unlock is the combination. You can now build a collection from conditions, refine it by hand, exclude specific products, reference other collections, and layer in app sources — all in one collection, without maintaining separate lists. The either/or era is over.

Variant-level targeting

The second big change: collections can now target specific variants, not just whole products.

Previously a collection included a product or it didn't. Now you can include the summer colorway of a jacket in a "Summer" collection without dragging in every other variant. For stores with rich variant catalogs — apparel, configurable products, multi-format goods — this is a real precision upgrade for curated merchandising.

Native AI merchandising

Shopify also brought AI merchandising natively into collections (Summer '26):

• AI Collection Sort — orders products on a collection page by their predicted probability of converting, so your best performers surface automatically instead of being hand-sorted.
• Predictive cross-sell blocks — surface complementary items based on cart contents.
• A merchandising insights panel in the admin — visibility into how collections are performing.

This is CRO built into the collection itself. Instead of manually reordering products or paying for a sort app, the platform can now optimize collection order toward conversion — and you should A/B test it to confirm the lift for your store. (Native testing makes that easy — see Shopify native A/B testing vs. apps.)

What this means for merchants

• Nothing breaks. Your existing smart and custom collections keep working; migration is incremental.
• But rebuild your clunky ones. Any collection you held together with tag hacks, duplicate lists, or manual clean-up is a candidate to rebuild cleanly with combined sources + exclusions.
• Merchandise more precisely. Variant targeting lets you curate at the variant level — big for apparel and configurable catalogs.
• Let AI do the sorting. Turn on AI Collection Sort, test it, and stop hand-ranking products.
• Clean product data matters more than ever. AI sort and predictive cross-sell are only as good as your product data and attributes — the same clean, structured data that wins AI discovery.

What it means for developers and apps

If you run custom apps or integrations, this is a version update to plan for. The new model is in the GraphQL Admin API 2026-07. If your app reads, writes, renders, syncs, or checks collection membership, update to 2026-07 so it stays aligned with the collections merchants build going forward. Existing collections keep working, so you can migrate incrementally — but don't leave it: collections created with the new combined-source model won't be fully represented by older API versions. (For the broader "when to build an app vs. a Function" decision, see Shopify Functions vs Apps.)

How to take advantage

1. Audit your collections — flag the ones built with workarounds (manual clean-up of smart collections, duplicate lists, tag hacks).
2. Rebuild them with combined sources — conditions + manual + exclusions in one place.
3. Use variant targeting where curation matters (colorways, formats, editions).
4. Enable AI Collection Sort and A/B test it against your current sort order.
5. Update custom apps to GraphQL Admin API 2026-07.

The bottom line

Collections were one of the more rigid parts of Shopify merchandising — and in 2026 they became one of the most flexible. The Collection Sources model, variant targeting, and native AI sorting together turn collections from static lists into a real merchandising engine. Nothing forces you to move today, but the stores that adopt the new model will merchandise more precisely and convert better.

We help Shopify brands modernize their merchandising — rebuilding collections on the new model, wiring up variant-level curation and AI sort, and updating custom apps to the latest API.
