Use the shortcode `[nwsfilter_product_filter]` in any page or post, or add it to your theme template using `` ### Can I display selected filters separately? Yes! Use the shortcode `[nwsfilter_selected_filters]` to display only the active/ selected filters with remove buttons. This is useful when you want to show filters in a different location or when you’ve hidden them from the main filter form. ### How do I change the order of filters? In the admin settings (Settings > Product Filter), you can drag and drop the filter items to reorder them. The order you set will be reflected on the frontend. ### Can I customize the appearance? Yes! The plugin includes comprehensive CSS classes that you can override in your theme’s CSS file. All main elements have specific classes like `.nws-filter`, `. filter-group`, `.range-slider`, etc. ### Does it work with AJAX? The filtering uses URL parameters and page reloads. The interface includes a loading indicator for better user experience. ### Can I hide selected filters from the main filter form? Yes! In the admin settings, enable “Hide Selected Filters in Filter Form” and use the `[nwsfilter_selected_filters]` shortcode to display them elsewhere. ### How do I enable category auto-expand? In Settings > Product Filter, check the “Auto-expand Parent Categories” option. This will automatically expand parent categories when viewing a subcategory. ### What WooCommerce versions are supported?
