Why Your Business Needs This Page

  • Better Catalog Filtering: customers find the desired product faster.
  • Less Duplication: a clean filter structure improves navigation quality.
  • Relevance Control: easily identify empty/dead filters.
  • Quick Scaling: bulk actions speed up the content team's work.

Main Buttons

  • Language Switcher - display and edit filters in the selected language.
  • "Empty Groups" - find groups without useful values.
  • "Filters Without Products" - find filters not linked to products.
  • "Duplicate Filters" - find repetitions in the structure.
  • "Manage Values" - open detailed management of group filters.
  • Group Edit Icon - changes group names across languages.
  • Group Delete Icon - deletes the group along with its filters (caution).

Actions in Value Management

  • Edit Filter Name (by languages).
  • Merge Filters (merge duplicates into a target filter).
  • Move Filter to Group (move).
  • Delete Filter.
  • Bulk Selection and bulk operations within a group.
  • View Products/Categories through quantity badges.

Step-by-Step Workflow

  1. Select the desired language in the switcher.
  2. Run an audit: "Duplicates", "Empty Groups", "Filters Without Products".
  3. Open the problematic group through "Manage Values".
  4. Merge duplicates and move filters to the correct groups.
  5. Delete truly unnecessary filters/groups after usage verification.
  6. Check the result in categories and on the storefront.

Practical Tips

  • Before deleting a group, check if its values are needed in active categories.
  • First merge duplicates, then clean up filters without products.
  • Keep consistent filter names across all languages for stable analytics.
  • After bulk changes, check navigation in top categories.
Important: merging and deleting massively change the filter structure. Before confirming actions, verify the merge target and the list of selected records.

What This Brings to Your Business

  • A clearer filtering experience for the customer.
  • Less technical noise in the catalog.
  • Faster servicing of a large assortment.
  • Better quality of search and product navigation.
