Syntax
[UxmlElement]
public class Accordion : BaseVisualElement, IEventHandler, IResolvedStyle, ITransform, ITransitionAnimations, IExperimentalFeatures, IVisualElementScheduler, IContextOverrideElement, IAdditionalDataHolder
Remarks

The Accordion component is a versatile UI element that organizes content into collapsible sections. Each section consists of a header and content area that can be toggled open or closed. This pattern is particularly useful when you need to present multiple sections of content in a limited space.

The component supports both single-expansion (exclusive) and multi-expansion modes, making it suitable for various use cases such as FAQs, settings panels, or navigation menus.

Note: The Accordion component requires AccordionItem children to function properly. Each AccordionItem represents a collapsible section within the Accordion.
