How can I merge individual products into size variants on product pages?

Shopify Discussion

Topic summary

Request to consolidate many size-specific products into a single product page with size variants, where switching variants updates images, description, and metafields to match that size. Also wants variants to appear as individual products on collection pages.

Key requirements:

  • Variant selection should dynamically change the image gallery and content per size.
  • Descriptions and metafields must be variant-specific.
  • Collection pages should list each size as its own product entry (or equivalent visibility).

Implementation question:

  • Seeks guidance on whether this is achievable with a Shopify app and asks for app recommendations, or advice on the best approach to build it.

Reference:

  • Provides a Lululemon product URL demonstrating desired behavior (variant-driven page with size and color parameters).

Status:

  • No solutions or decisions yet; looking for recommendations and an approach. Discussion remains open.

I have a bunch of individual products that are specific to size. I want these existing products to merge into or link to a product page that can show variants of other size options. when they change the variant, I want the image gallery and descriptions and Metafields to change to match that product. Is this something I can achieve with an app and if so any suggestions? Or what is the best way to approach this?

This is an example: https://shop.lululemon.com/p/women-pants/Align-Pant-Tall/_/prod9410067?color=31382&sz=2

The variants also show as individual products on the collection pages
