Sibling products

Sibling products let shoppers jump between related SKUs (colors, scents, kits) without using a single multi-variant product.

​

Setup

1. Create a product reference list metafield (or use the metafield key expected by the Sibling products block — check block settings).
2. On each product, add the other siblings to that metafield (usually bidirectional).
3. In the product template, enable the Sibling products block.
4. Configure labels and option presentation.
5. Preview: selecting a sibling should navigate to that product URL.

​

Tips

• Keep sibling sets small and consistent.
• Use clear swatch or label media so differences are obvious.
• Sibling navigation is separate from FBT add-ons.
