Magento 2 Infinite Scroll is a feature or extension for the Magento 2 e-commerce platform. It provides a seamless scrolling experience on product listing pages, eliminating the need for pagination. Instead of loading a new page when users reach the end of the product list, the infinite scroll feature automatically loads the next set of products as the user scrolls down. With Infinite Scroll Magento 2 customers can continue browsing products without the interruption of clicking through different pages. It simplifies the navigation process, improves user experience, and encourages users to explore more products. This feature is particularly useful for online stores with a large number of products or categories.
