YITH WooCommerce Ajax Product Filter lets you filter the product catalog by attribute, price, stock, rating and much more.
The combined use of these two plugins allows inheriting the colors, labels, and images configured with YITH Color, Image & Label Variation Swatches for WooCommerce as configuration of the filtering terms, so you don’t have to re-create them from scratch in the filter. This applies to 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, Image & Label Variation Swatches.
When enabling the option “Show variations as separate products” in YITH Color, Image & Label Variation Swatches, each variation will be shown as a separate product.
The filter will also be applied in this case, and will show all products (variations) that match the filter.
