Configure Layered Navigation from Magento 2 default is designed as a convenient sitemap on your Magento 2 store. The navigation is usually placed on the left of the category page with list of categories and price range. Thus, instead of going around your store, the customers only need to describe their demands through the criterias filter, and they will get the desired items very quickly. However, if you want to give more criterias for the searching as well as enhance customer’s experience on your site, you can refer to Magento 2 Layered Navigation extension, an advanced filter from Mageplaza.
