Janssen Fast Filters is built differently. It delivers fast AJAX product filtering with clean architecture, optimized queries, AND logic, and auto-apply — without page reloads and without unnecessary bloat. An ideal alternative to the default WooCommerce layered navigation widget. ### Core Features (Free) * AJAX filtering — no page reloads * AND filter logic (combine multiple attributes intelligently) * Auto-apply filters (no “Apply” button required) * Category filter with optimized hierarchical rendering * Product attribute filters (color, size, custom attributes, etc.) * Price range slider with min/max inputs * Sort by price, popularity, rating, or date * Mobile-friendly slide-in filter panel * Active filters display with one-click removal * Shareable filter URLs: Back, reload, and shared links restore filters, sort, and page * Server-rendered first page of products that also works without JavaScript * Page-cache and SEO friendly: no expiring nonce for visitors, and filtered URLs are not indexed * Gutenberg block for easy placement * Fully translatable ### Why Choose Janssen Fast Filters? * Performance-first architecture * Optimized database queries * Lightweight — no frameworks, no unnecessary dependencies * Built for scalability and large product catalogs * Clean, maintainable codebase * Accessible (ARIA labels + keyboard navigation) * Mobile-first UX Designed for developers, store owners, and growing WooCommerce businesses that care about speed and maintainability. ### Pro Extension The Pro version adds advanced features for growing stores: * Theme-aware WooCommerce product rendering * Filter presets * Live product counts * Query caching layer * Advanced customization options Built for high-traffic stores and larger catalogs. ## Screenshots [[ [[ [[ [[ ## Blocks This plugin provides 1 block. * Product Filter A high-performance product filter for WooCommerce. ## Installation 1.

each block has “Keep filters in the URL” and its own URL key * Blocks render their first page of products (and Pro counts) on the server, so the first view needs no request * Without JavaScript, filters, sort, and pagination work as a form and links in every layout * Cached pages keep working: visitors’ pages no longer embed an expiring REST nonce; public caching of product requests is opt-in * Filtered and sorted URLs are served with noindex, follow * Added catalog change events so caches and page caches invalidate only what a change affects, and a purge action for hosts * Live counts are computed in one SQL statement per filter group, so catalogs above 10,000 products get counts too * Added opt-in request metrics (wp janssenff metrics) and Server-Timing for store managers * A page past the last one now reports the real product total * Filter inputs are now named after URL parameters and use slugs; see the upgrade notice #### 1.4.0 * Added a public facet-count operation that shares the product query’s category, attribute, price, archive, and AND/OR rules * Added optional count context on product requests and a query/cache policy that keeps third-party query changes safe * Added strict filter-selection validation for presets * Added per-block live count, sticky sidebar, sticky top bar, and sticky offset settings for compatible extensions * Improved the filter panel: focus moves in and out correctly, Escape closes it, page scrolling is restored, and double submits are prevented * Added the Phase 4 integration and migration guide #### 1.3.0 * Added a public, versioned renderer context for per-block renderer selection * Added granular product and empty-state lifecycle events for renderer adapters * Kept renderer selection separate from product queries, filter state, and cache keys * Preserved deterministic Free cards when a renderer or adapter is unavailable * Added public integration documentation and runtime coverage for third-party renderers #### 1.2.0 * Added a versioned product-render handoff for compatible extensions * Kept Free in control of requests, state, pagination, loading, and fallback cards * Preserved generic cards when Pro or a compatible theme renderer is unavailable * Kept cached responses free of stale extension or theme markup #### 1.1.1 * Fixed duplicate DOM and bootstrap IDs when multiple filter blocks render on one page #### 1.1.0 * Added canonical per-block frontend state with server-rendered bootstrap data * Added root-scoped lifecycle events, extension actions, and versioned PHP hooks * Preserved WooCommerce archive context throughout REST queries and cache keys * Isolated requests across multiple filter blocks and prevented stale responses from rendering * Fixed pagination controls submitting the filter form and resetting active filters * Retained compatibility shims for existing integrations #### 1.0.7 * Fixed the no-results message remaining hidden after a successful zero-product AJAX response * Verified compatibility with WordPress 7.1 and WooCommerce 11.0.1 #### 1.0.6 * AND filter logic and auto-apply are now fully available in the free version * Removed Presets UI from Free editor (visible only when Pro extension is active) * Fixed showPresets block attribute default to false * WordPress.org compliance improvements #### 1.0.5 * Renamed plugin to Janssen Fast Filters for WooCommerce * Category hierarchy rendered as optimized accordion tree (single-query, N+1 free) * UX polish: improved spacing and animation refinements * Added Requires Plugins header for compliance #### 1.0.4 * Renamed hooks to janssenff_* prefix for compliance #### 1.0.3 * Trademark compliance updates #### 1.0.2 * Improved loading and no-results states * Better mobile touch targets * Removed static term counts for cleaner UX * Code cleanup and compliance improvements #### 1.0.0 * Initial release * AJAX product filtering * Category, attribute, and price filters * Mobile-responsive design * Gutenberg block support ## Meta * Version **1.5.0** * Last updated: **3 weeks ago** * Active installations: **Fewer than 10** * WordPress Version: ** 6.3 or higher ** * Tested up to: **7.1.3** * PHP Version: ** 8.0 or higher ** * Language * [English (US)](https://wordpress.org/plugins/janssen-fast-filters-for-woocommerce/) * Tags: * [ajax filter](https://en-ca.wordpress.org/plugins/tags/ajax-filter/)[ecommerce](https://en-ca.wordpress.org/plugins/tags/ecommerce/) [layered nav](https://en-ca.wordpress.org/plugins/tags/layered-nav/)[product filters](https://en-ca.wordpress.org/plugins/tags/product-filters/) [woocommerce](https://en-ca.wordpress.org/plugins/tags/woocommerce/) * [Advanced View](https://en-ca.wordpress.org/plugins/janssen-fast-filters-for-woocommerce/advanced/) ## Ratings No reviews have been submitted yet.
