Sidebar is a navigational panel often used used for seamless, ergonomic navigation within an app interface. It's typically used to house secondary actions, additional information, or a sub-navigation menu related to the active page or section.

Sidebars can be static or collapsible depending on the design requirements and screen size. By providing easy access to supplemental content or functionality, the Sidebar component enhances user experience by offering a structured, organized way to present additional information or actions.
