Component name

The name MuiAccordionSummary can be used when providing default props or style overrides in the theme.


childrennodeThe content of the component.
classesobjectOverride or extend the styles applied to the component. See CSS API below for more details.
expandIconnodeThe icon to display as the expand indicator.
focusVisibleClassNamestringThis 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.

The ref is forwarded to the root element.
Any other props supplied will be provided to the root element (ButtonBase).


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