ITG Filter Easy

ITG Filter Easy is an Elementor widget for WooCommerce product filtering. It works as a sidebar filter — it does not output products itself, but modifies the existing WooCommerce Products widget output via URL parameters and pre_get_posts, with full AJAX support (no page reload).

Key features:

• Filter by categories, attributes (pa_*), price range, brand, stock status, sale, and text search
• AJAX update — product list refreshes without page reload
• Faceted counts — option counts update after each filter change
• Browser history support — Back / Forward navigation works correctly
• Brand currency conversion — prices stored in brand currency are auto-converted to the WooCommerce active currency using a configurable exchange rate feed
• Auto-filter mode — applies filters instantly on change without a submit button
• 5 translations bundled: Russian, German, French, Spanish, Chinese
• 16 developer filter hooks
• HPOS (High-Performance Order Storage) compatible
