Bundle Builder
Build a "build your own box" page where customers pick their own products.
Welcome to the Bundle Builder docs.
A Bundle Builder is a page of its own where customers assemble a custom bundle — "Build your own gift box: choose 3 candles, 2 soaps, and 1 bath bomb. Save 15%." You define the categories, the box sizes, and the discount; customers do the picking.
Bundle Builder is the BYOB ("build your own box") half of Foxr on the Shopify App Store.

Two builder types
Every builder is one of two types, chosen when you create it and fixed after that:
| Landing page builder | Product page builder | |
|---|---|---|
| Lives on | A page of its own | The bundle's own product page |
| Placement | Auto-created page, app block, or embed code | None needed — it's part of the product page |
| Layout | Categories, tabs, sidebar | Product catalog or product slots |
The rest of these docs default to the landing page type; see Product page builder for what's different about the other one.
