What theme app extension bundle widgets means in Kitforge
Rendering happens in JavaScript fetched via the app proxy (/apps/kitforge/offers), keeping Liquid under Shopify's size limits.
- fixed kit bundles — combine known products into one priced offer
- frequently bought together (FBT) — product-page add-on recommendations
- quantity breaks — tiered volume discounts when shoppers buy more units
Setup workflow
Kitforge uses a type-first editor with a readiness checklist before publish. Each bundle type has its own steps, but the operating loop is consistent.
- Enable the Kitforge auto bundle card app embed in the theme editor.
- For manual placement, add a block to a product template and paste the bundle ID.
- Set widget position: below add to cart (default), above add to cart, or manual block only.
- Avoid duplicating widgets — configure coexistence rules when multiple offers target one PDP.
