LoadingButton API

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

Import

import LoadingButton from '@material-ui/lab/LoadingButton';
// or
import { LoadingButton } from '@material-ui/lab';

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

Component name

The MuiLoadingButton 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 button.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
disabled	bool	false	If true, the button is disabled.
pending	bool	false	If true, the pending indicator is shown.
pendingIndicator	node	<CircularProgress color="inherit" size={16} />	Element placed before the children if the button is in pending state.
pendingPosition	'start' | 'end' | 'center'	'center'	The pending indicator can be positioned on the start, end, or the center of the button.

The ref is forwarded to the root element.

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

CSS

Rule name	Global class	Description
root	.MuiLoadingButton-root	Styles applied to the root element.
pending	.MuiLoadingButton-pending	Styles applied to the root element if pending={true}.

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 Button component are also available. You can take advantage of this behavior to target nested components.
