WooCommerce Variation Swatches is the most popular attribute variation plugin in the WordPress plugin directory.
WooCommerce Variation Swatches Pro is a simple plugin, but it does a great job. Turns a drop-down list of product attributes into beautiful patterns. This means that you can turn a drop-down list of product choices into patterns of colors, buttons, radios and images.
Consequently, the plugin greatly expands the possibilities of variations. Users do not need to open the drop-down selection box and see which options are available for the variable product. Without clicking unnecessary clicks and without spending extra time, they can quickly select the desired option.
