API documentation for the React AccordionSummary component. Learn about the available props, and the CSS API.

You can learn about the difference by reading this guide on minimizing bundle size.

Component name

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

Props

Name	Type	Description
children	node	The content of the accordion summary.
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 a person know which element has the keyboard focus. The class name will be applied when the element gain the focus through a 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).

Inheritance

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.

CSS

Rule name	Global class	Description
root	.MuiAccordionSummary-root	Styles applied to the root element.
expanded	.Mui-expanded	Pseudo-class applied to the root element, children wrapper element and `IconButton` component if `expanded={true}`.
focusVisible	.Mui-focusVisible	Pseudo-class applied to the ButtonBase root element if the button is keyboard focused.
disabled	.Mui-disabled	Pseudo-class applied to the root element if `disabled={true}`.
content	.MuiAccordionSummary-content	Styles applied to the children wrapper element.
expandIconWrapper	.MuiAccordionSummary-expandIconWrapper	Styles applied to the `expandIcon`'s wrapper element.

You can override the style of the component using one of these customization options:

With a rule name of the classes object prop.
With a global class name.
With a theme and an styleOverrides property.

If that isn't sufficient, you can check the implementation of the component for more detail.
