ExpansionPanelSummary API

The API documentation of the ExpansionPanelSummary React component. Learn more about the props and the CSS customization points.

Import

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

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

⚠️ The ExpansionPanelSummary component was renamed to AccordionSummary to use a more common naming convention.

You should use import { AccordionSummary } from '@material-ui/core' or import AccordionSummary from '@material-ui/core/AccordionSummary'.

Component name

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

Props

Name	Type	Default	Description
children	node		The content of the expansion panel 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.
IconButtonProps	object		Props applied to the IconButton element wrapping the expand icon.
onFocusVisible	func		Callback fired when the component is focused with a keyboard. We trigger a onFocus callback too.

The ref is forwarded to the root element.

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

CSS

Rule name	Global class	Description
root	.MuiExpansionPanelSummary-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 root element if focused={true}.
disabled	.Mui-disabled	Pseudo-class applied to the root element if disabled={true}.
content	.MuiExpansionPanelSummary-content	Styles applied to the children wrapper element.
expandIcon	.MuiExpansionPanelSummary-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:

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

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

Inheritance

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