A boiler category gets different filters than a tap category, without any configuration. #### What you get * **Automatic filters per page** – on category, shop, tag and brand pages. A filter only appears when it actually helps (at least two options, enough products covered). * **Instant AJAX filtering** – results, counts and pagination update without a page reload, using a light response with only the products. Back and forward buttons work, and every filtered page has its own URL. * **Desktop filter bar** – compact drop-down panels above the product list, with removable filter chips and “clear all”. * **Mobile filter sheet** – a full-height bottom sheet with large touch targets, a live “Show 24 products” button, swipe down or Esc to close. * **Price slider** and **number sliders** for numeric attributes (litres, watts, millimetres…). * **Sorting and products per page** in the same bar, replacing the default WooCommerce controls. * **Live counts** next to every option; options without results disappear. * **Fast on large shops** – a dedicated attribute index and the WooCommerce lookup tables, with smart caching. Works with page caches such as SiteGround Optimizer, WP Rocket and LiteSpeed. * **SEO-safe** – filtered and sorted variants get `noindex, follow` and filter options are not crawlable links, so search engines do not waste time on endless filter combinations. * **Works without JavaScript** – the filter is a normal form, AJAX is an enhancement. * **Switch filter types on or off** for the whole shop (brand, price, sale, rating, stock…), and hide attributes you never want as a filter. * **Clean up messy data** – merge attribute values that mean the same thing (“Heating& cooling” / “Heating & air conditioning”) or hide values, for all products at once. Codes such as EAN or SKU never become a filter. * **Accent colour** setting to match your brand. * **Translation-ready** – follows the site language (also with WPML and Polylang) or can be forced. * Brand support for WooCommerce Brands, Perfect Brands for WooCommerce and YITH Brands. * Classic themes (Astra, Enfold, Flatsome, OceanWP, Kadence, Storefront…) and block themes. * Compatible with WooCommerce HPOS. #### FilterSmith Pro [Pro](https://filtersmith.com/) is a separate add-on for shops that need more: * **Smart text recognition** – reads volume, power, size, voltage, flow rate, colour and material from product titles and descriptions (including specification lines and tables), so you get useful filters even when your products have no attributes. * **Custom filter sets per category** – choose, order and rename the filters for any category yourself. * **One global order and names** for the filters on all pages. * **German, French and Spanish** for the filters, the settings and the text recognition. * **Colour swatches** next to colour options. * Priority email support. The free plugin is complete on its own and never limits the number of filters, products or categories. ## Screenshots [⌊The filter bar above the product list, with drop-down panels, chips and sorting.⌉⌊ The filter bar above the product list, with drop-down panels, chips and sorting.⌉[ The filter bar above the product list, with drop-down panels, chips and sorting.

Install and activate the plugin through **Plugins > Add New** (WooCommerce must be active). 2. Go to **WooCommerce > FilterSmith** and click **Build index**. This analyses your products once; afterwards the index updates itself whenever you save or import a product. 3. Open a product category in your shop. The filter bar appears above the product list. 4. Using a page cache? Clear it once after changing settings. Want the filter somewhere else? Choose **Placement: only via shortcode** and add`[ filtersmith]` to your category template. ## FAQ ### Do I have to set up filters for every category? No. The plugin chooses the filters per page. You can hide attributes you never want as a filter and set the minimum number of products a page needs before filters are shown. ### Why does a category show no filters? Pages with fewer products than the minimum (default 8) get no filter bar, and neither do parent categories where WooCommerce only shows subcategories. Both can be changed in the settings. ### Which attributes are used? All WooCommerce product attributes, global and custom. Attributes with numbers ( such as “100 L” or “2000 W”) get a slider; text attributes get checkboxes. ### My products have no attributes. Can I still filter by size or colour? Yes, with Pro. Its text recognition reads values such as “150 liter”, “2,5 kW”, “ Ø 110 mm”, “230V”, “black” or “stainless steel” from product titles, and specification lines such as “Volume: 80 L” or a specification table from product descriptions. ### Does it work with my theme? It hooks into the standard WooCommerce product loop and works with classic and block themes. If your theme uses custom markup for the product list, the CSS selectors can be changed with the `cwcf_js_selectors` filter. ### Does it slow down my shop? No. Filter counts come from an indexed table and the WooCommerce lookup tables, and the unfiltered view of each page is cached. On classic themes each filter change loads a light response with only the filter and the products (no header, menus or footer), which is several times smaller than the full page. When you are logged in as an administrator, the page source contains a comment with the time and number of database queries the filter used. ### Is it translatable? Yes. All texts can be translated on translate.wordpress.org; WordPress installs the translations automatically. ### Will it change my products? Never. The plugin only reads your products. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “FilterSmith – Product & Category Filters for WooCommerce” is open source software.
