Props

Name	Type	Default	Description
action	func \| { current?: { focusVisible: func } }		A ref for imperative actions. It currently only supports `focusVisible()` action.
color	'danger' \| 'neutral' \| 'primary' \| 'success' \| 'warning' \| string	'neutral'	The color of the component. It supports those theme colors that make sense for this component. To learn how to add your own colors, check out Themed components—Extend colors.
component	elementType		The component used for the root node. Either a string to use a HTML element or a component.
disabled	bool	false	If `true`, the component is disabled.
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.
loading	bool	false	If `true`, the loading indicator is shown and the icon button becomes disabled.
loadingIndicator	node	<CircularProgress />	The node should contain an element with `role="progressbar"` with an accessible name. By default we render a `CircularProgress` that is labelled by the button itself.
size	'sm' \| 'md' \| 'lg' \| string	'md'	The size of the component. To learn how to add custom sizes to the component, check out Themed components—Extend sizes.
slotProps	{ loadingIndicator?: func \| object, root?: func \| object }	{}	The props used for each slot inside.
slots	{ loadingIndicator?: elementType, root?: elementType }	{}	The components used for each slot inside. See Slots API below for more details.
sx	Array<func \| object \| bool> \| func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
variant	'outlined' \| 'plain' \| 'soft' \| 'solid' \| string	'plain'	The global variant to use. To learn how to add your own variants, check out Themed components—Extend variants.

The ref is forwarded to the root element.
