Auto Close in React Sidebar component

03 Dec 2021 / 1 minute to read

Sidebar often behaves differently on mobile display and differently on desktop display. It has an effective feature that offers to set it in opened or closed state depending on the specified resolution. This is achieved through mediaQuery property that allows you to set the Sidebar in an expanded state or collapsed state only in user-defined resolution.
