Props

Props of the ButtonBase component are also available.

Name	Type	Default	Description
children	node		The content of the component.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
color	'inherit' \| 'primary' \| 'secondary' \| 'success' \| 'error' \| 'info' \| 'warning' \| string	'primary'	The color of the component. It supports both default and custom theme colors, which can be added as shown in the palette customization guide.
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.
disableElevation	bool	false	If `true`, no elevation is used.
disableFocusRipple	bool	false	If `true`, the keyboard focus ripple is disabled.
disableRipple	bool	false	If `true`, the ripple effect is disabled. ⚠️ Without a ripple there is no styling for :focus-visible by default. Be sure to highlight the element by applying separate styles with the `.Mui-focusVisible` class.
endIcon	node		Element placed after the children.
fullWidth	bool	false	If `true`, the button will take up the full width of its container.
href	string		The URL to link to when the button is clicked. If defined, an `a` element will be used as the root node.
size	'small' \| 'medium' \| 'large' \| string	'medium'	The size of the component. `small` is equivalent to the dense button styling.
startIcon	node		Element placed before the children.
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	'contained' \| 'outlined' \| 'text' \| string	'text'	The variant to use.

The ref is forwarded to the root element.
