Filter not working at frontend

Shopify Discussion

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)
  • Navigation menus don’t provide access to metafield filters
  • Manual URL filtering attempts are unsuccessful

  • Verify Shopify supports metafield filtering for the store
  • Confirm metafields are created correctly
  • Ensure metafields are properly assigned to products
  • Consider using Shopify’s “Search & Discovery” app
  • Check theme compatibility with metafield filtering

The issue remains unresolved with no definitive solution provided yet.
