Filter not working at frontend

Topic summary

A user is experiencing issues with product filtering based on metafields in their Shopify theme. The theme documentation indicates it supports metafield-based filtering, but when attempting to filter using a URL parameter (filter.p.m.custom.parts=demo), all products display instead of the filtered subset.

Key Details:

  • The theme claims to support metafield filtering (shown in screenshots)

  • Verify Shopify supports metafield filtering for the store

  • Ensure metafields are properly assigned to products
  • Consider using Shopify’s “Search & Discovery” app
  • Check theme compatibility with metafield filtering
