How to display specific pack size options based on product size selection?

Topic summary

Problem: A Shopify product uses three options (Size, Color, Pack Size). Only Size 8.5x12 should allow Pack Size “case of 200,” and only Size 6x10 should allow “case of 400.” The goal is to show only the applicable Pack Size after a Size is chosen.

Attempted approach: A responder linked Shopify’s guide for hiding sold‑out variants in vintage themes. The original poster followed the steps but reported it didn’t work for this conditional display need.

Proposed solution: Another responder recommended a third‑party app (Easify Product Options) using Conditional Logic—rules that show/hide option values based on earlier selections. They suggested setting rules to show “Case of 200” only when Size = 8.5x12 and “Case of 400” only when Size = 6x10, and to use buttons or radio buttons instead of dropdowns for clarity.

Artifacts: Screenshots were provided to demonstrate configuration.

Status: No confirmation of implementation success; the thread remains open with the app‑based conditional logic as the current suggested path.
