Filters not appearing

Dost reads filters from Shopify's filter system. If the sidebar is empty, the issue is upstream.

Check 1 — Filters configured?

Shopify admin → Online Store → Navigation → Filters.

You should have at least one filter listed (e.g., Availability, Price, Color, Size). If empty, click Add filters and pick the ones you want.

Check 2 — Filters apply to this collection?

Some filters can be scoped per collection. Make sure the filters you've added apply globally or to this specific collection.

Check 3 — Variants have the right metafields?

Color filter requires variants to have a Color option. Size filter requires Size. The variant option names must match Theme settings → Product → Variant option name matching (default lists are localised — color, colour, renk, …).

If your shop uses non-standard option names, add them to the Color / Size lists in Theme settings.

Check 4 — Filter values exist for products in scope?

Empty filter values are hidden. If "Size: M" doesn't appear in the sidebar, no product in the current collection / search results has Size = M.

Filter not auto-applying?

Each checkbox has an onchange handler that navigates immediately to the filter URL. If clicking does nothing:

• Open browser console — JS errors block the handler
• Disable any third-party app that might be intercepting clicks
