YITH WooCommerce Ajax Product Filter allows filtering the product list basing on their attributes or price. The filter is applied by Ajax, therefore without the need to refresh the page to show the search result.
The combined use of these two plugins allows using colors, labels, and images configured with YITH Color and Label Variations for your terms when creating filters of Color swatches and Label/Image types.
Specifically, by disabling the option Customize terms, the plugin will recover the options configured for the terms with YITH Color and Label Variations.
When enabling the “Show shingle variations in loop” option in the Color and Label plugin, each variation will be shown as a separate product.
The filter will also be applied in this case, and will show all product (variations) that match the filter.
For further details about YITH WooCommerce Color and Label Variations, please refer to the official documentation.
