import AccordionSummary from '@material-ui/core/AccordionSummary';
// or
import { AccordionSummary } from '@material-ui/core';

You can learn more about the difference by reading this guide.

Component name

The MuiAccordionSummary name can be used for providing default props or style overrides at the theme level.


Name Type Default 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 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.
IconButtonProps object {} Props applied to the IconButton element wrapping the expand icon.

The ref is forwarded to the root element.

Any other props supplied will be provided to the root element (ButtonBase).


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}.
focused .Mui-focused Pseudo-class applied to the ButtonBase root element if the button is keyboard focused.
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.
expandIcon .MuiAccordionSummary-expandIcon Styles applied to the IconButton component when expandIcon is supplied.

You can override the style of the component thanks to one of these customization points:

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


The props of the ButtonBase component are also available. You can take advantage of this behavior to target nested components.
