OpenFilter¶

Layered navigation for Magento 2 and Hyvä. Free and MIT, built on the OpenSearch Magento already ships.

• Multi-select filters with correct counts: options of a filter you use are counted as if it were not set, in one search request.
• AJAX that Varnish can cache: a filter click fetches the same URL a normal page load would, so the page cache serves it; CSP-clean on Hyvä, no reload, back button and scroll restored.
• Works without JavaScript: every option is a real link, sliders are forms.
• Sliders and built-in filters: price (display currency and tax aware) and decimal sliders, rating, in stock, on sale, new.
• Mobile drawer with "Show 123 products" counted before you apply.
• SEO rules: readable URL names, one canonical URL per page (301), robots and canonical tags, nofollow and a limit on combined values.
• Admin with diagnostics: Filters grid, a form per filter, "Why is this filter not showing?", openfilter:doctor.
