MRZ Product Filter Exp

MRZ Product Filter is a minimalist product filter for WooCommerce. It builds a filter panel from your product categories, attributes and tags, plus a price slider, and lets shoppers narrow down the shop or category archives with instant AJAX updates. A chosen “color” attribute is rendered as color swatches.

Each filter set is configured from a dedicated Custom Post Type and can be displayed automatically on the shop / archives, or placed manually with a shortcode. The markup is intentionally minimal (wireframe, black & white) so you can style it to match your theme.

Features

• Filter by product categories, tags, brands and product attributes (checkboxes, radio buttons or dropdowns).
• Price range slider (min / max).
• Color swatches for a chosen attribute — the color is stored on each attribute term and reusable.
• AJAX refresh of the product loop, with native URL parameters (shareable, SEO-friendly) and a no-JavaScript fallback that filters through WooCommerce natively.
• Collapsible sections (native <details>), with a per-section and global “expanded by default” setting.
• Automatic display on the shop and category / tag archives (left column or above the products), or manual placement with [mrzpfe_product_filter id="X"].
• Multiple filter sets via a dedicated Custom Post Type — a different configuration per context.
• Translation-ready (text-domain mrz-product-filter-exp, .pot file provided).

Requirements

• WordPress 6.3 or later, PHP 7.4 or later.
• WooCommerce.
