Props

Props of the ButtonBase component are also available.

Name	Type	Description
children	node	The content of the component.
classes	object	Override or extend the styles applied to the component. See CSS API below for more details.
expandIcon	node	The icon to display as the expand indicator.
focusVisibleClassName	string	This prop can help identify which element has keyboard focus. The class name will be applied when the element gains the focus through keyboard interaction. It's a polyfill for the CSS :focus-visible selector. The rationale for using this feature is explained here. A polyfill can be used to apply a `focus-visible` class to other components if needed.
sx	Array<func \| object \| bool> \| func \| object	The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.

The ref is forwarded to the root element.

Inheritance

While not explicitly documented above, the props of the ButtonBase component are also available in AccordionSummary. You can take advantage of this to target nested components.
