Add Complementary Products on Cart Page

Topic summary

Request to show complementary products (cross-sell items) defined in Shopify Search & Discovery on the Cart page, triggered when a related product is in the cart, without using any third‑party app. Aim: on-cart upsell/optimization; tags hint at possible use of Shopify Scripts or theme code.

Key details:

  • Constraint: no apps; seeking native or theme-based solution (e.g., Liquid/JS) that pulls Search & Discovery complementary recommendations.
  • Scope: display conditionally per cart contents on the Cart page.

Information gaps:

  • No code, screenshots, or specific store setup provided.
  • Unclear whether Shopify Plus features (e.g., Scripts) are required or if standard Online Store 2.0 capabilities suffice.

Status: unanswered and unresolved. The asker seeks confirmation of feasibility and guidance on implementation approaches using native Shopify functionality.
