A Sidebar Menu is a user interface element commonly found in websites and applications. It typically appears on the side of the screen and provides easy access to various sections or features. Users can click on items in the sidebar to navigate quickly without having to return to a main menu. Sidebar menus can be either static or collapsible. A static sidebar remains visible at all times, while a collapsible sidebar can be hidden or shown with a click. This design helps improve user experience by organizing content and making navigation more intuitive, especially in complex applications like content management systems or e-commerce platforms.
