FollowInfinite-scrolling, also known as "endless scrolling" is a technique used most often by websites with JavaScript or AJAX to load additional content dynamically as users scroll down to the bottom of the webpage. Usually, when you drag down the sidebar to the bottom directly, you can see the "loading" sign, and the new content will be added into the page very soon:
