Display a list of expandable items with WinUI Accordion, a control with a compact interface that showcases hierarchical or multi-level content in a component and can expand and collapse specific views from a stacked list of views. The Accordion control helps organize your application's UI and optimize the use of screen real estate. It is used for navigation and it's optimized with responsive rendering and animation. The main advantage of using accordion is that it reduces page scrolling and allows the user to hide content that makes it appear less complicated. Complete with smooth animations, the accordion provides a visually compelling interface for a menu or a navigation bar in your WinUI application.
