Ajax-Enabled, Enhanced Layered Navigation. The Ajax-Enabled, Layered Navigation extension for WooCommerce provides a richer user experience for your customer and is particularly well suited for stores that have a lot of variable products or products with a number of attributes. Not only does the layered navigation use Ajax calls to reload content on the page, but the extension also provides a number of additional user-interface elements for the layered navigation, such as color swatches, size selectors and checkboxes. These useful options help you create a more meaningful, interactive experience for your user.
