Sieve – Faceted Filter for WooCommerce

Sieve gives your shoppers a fast, modern way to find products. They tick a few boxes, drag a price range, type a keyword, and the grid updates instantly with no page reload. It is built to feel effortless and to stay quick on large catalogs, with accessible widgets, a mobile filter drawer, and a rendering approach designed for Core Web Vitals: no layout shift when results change.

Everything runs against a pre-built index, so filtering stays fast even with thousands of products, and the counts next to each option update live as shoppers narrow down.

Filtering that feels instant:

• AJAX filtering with no page reload, and shareable, bookmarkable URLs
• Live dependent counts that update as filters are applied
• Active-filter chips, one-click reset, sorting and pagination built in

Every facet type you need:

• Checkboxes, radio buttons and searchable dropdowns
• Color and image swatches, hierarchical (tree) categories
• Autocomplete (searchable options) and an A-Z index
• Range sliders, keyword search, sort, pagination and reset

Filter by anything in your catalog:

• Categories, tags and product attributes
• Price, stock status and on sale

Predictive product search:

• An instant typeahead dropdown with thumbnails, prices, SKU and category matches, and full keyboard navigation

Fast and accessible by design:

• Pre-built index for quick filtered queries on large catalogs
• Mobile filter drawer with a sticky Apply bar
• Keyboard and screen-reader friendly widgets
• Core Web Vitals by design: no layout shift when results update

Easy to place and configure:

• Gutenberg “Sieve Filter” block, an Elementor “Sieve Filter” widget, and the [sieve] shortcode
• A visual facet builder in the admin: add, reorder and retype facets, set the layout, and rebuild the index

Development

The full, human-readable source for the compiled assets is included in this plugin under resources/, alongside the build tooling (package.json, scripts/build-wp.mjs). The compiled files under build/ are generated from those sources. To rebuild them:

1. npm install
2. npm run build

This uses Vite (admin and front-end scripts) and @wordpress/scripts (blocks). There is no obfuscation; every shipped asset can be regenerated from the included sources. The public source repository is also available at https://github.com/wppoland/sieve.

Translations

Sieve includes Polish, German and Spanish translations for the plugin interface. The text domain is sieve, so WordPress.org language packs can also override or extend these bundled translations.
