How to add product filters to WooCommerce

Choose filters that match how shoppers compare your products. Common choices are price, category, stock status, colour, size, brand and tags. Do not create an attribute for information WooCommerce already stores, such as SKU.

Use categories for broad product groups, tags for descriptive labels and global attributes for reusable characteristics such as size or colour. This keeps the filter list understandable as your catalogue grows.

Go to Products > Attributes. Add each reusable attribute, then add its terms, such as Small, Medium and Large under Size. Edit a product, open its Attributes section, choose Add existing, select the global attribute and assign the relevant terms.

Do not rely on a custom attribute created only inside one product if you want it to appear as a store-wide filter. For variable products, make sure the relevant attributes are assigned to the parent product and configured for variations where needed.

For the manual route, open Appearance > Editor > Design > Templates, select the Product Catalog template and add a Product Filters block near the Product Collection block. Add the individual filters you need, such as Price, Attribute, Category, Tag, Availability or Rating.

On a normal page rather than an archive template, place the Product Filters block inside the relevant Product Collection block. The filters are context-aware and need a product collection to know which products they should change.

Select each filter and choose its attribute or display options. Attribute filters can use a list or chips, with optional product counts. Add an Active Filters block if you want shoppers to see selected options and remove them individually or clear everything.

Select the surrounding Product Collection block and leave Reload full page disabled for updates without a full page reload. On mobile, decide whether to enable Collapse filters on small screens so the controls open in a drawer instead of taking over the page.

View the shop as a customer and test one filter at a time, combinations of filters, clearing selections, pagination and mobile display. Check that every expected product has the correct category, tag or global attribute assigned.

If a filter shows no results, first check that you used a global attribute rather than a product-only custom attribute. Imported products are another common failure point: an attribute may be visible on the product page but not registered correctly for filtering, or may have been assigned only to a variation. Also check that the filter is connected to the correct Product Collection; a filter placed on an unrelated homepage collection may not affect the shop catalogue.

If the block route is unavailable in your theme, or you need a more configurable sidebar with AJAX filtering, HUSKY – WooCommerce Products Filter is the quicker option. It can filter by attributes, categories, tags and price without a full page reload, and provides configurable layouts for desktop and mobile stores.

Install the plugin through the WordPress dashboard, activate it and configure the filters you want to show. Keep the same catalogue rules: use global attributes, assign terms consistently and test filters on category pages, product archives and small screens before publishing.
