Props

Props of the ButtonBase component are also available.

Name	Type	Default	Description
checked	bool	-	If `true`, the component is checked.
checkedIcon	node	<CheckBoxIcon />	The icon to display when the component is checked.
classes	object	-	Override or extend the styles applied to the component. See CSS classes API below for more details.
color	'default' \| 'primary' \| 'secondary' \| 'error' \| 'info' \| 'success' \| '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.
defaultChecked	bool	-	The default checked state. Use when the component is not controlled.
disabled	bool	false	If `true`, the component is disabled.
disableRipple	bool	false	If `true`, the ripple effect is disabled.
icon	node	<CheckBoxOutlineBlankIcon />	The icon to display when the component is unchecked.
id	string	-	The id of the `input` element.
indeterminate	bool	false	If `true`, the component appears indeterminate. This does not set the native input element to indeterminate due to inconsistent behavior across browsers. However, we set a `data-indeterminate` attribute on the `input`.
indeterminateIcon	node	<IndeterminateCheckBoxIcon />	The icon to display when the component is indeterminate.
inputProps	object	-	Attributes applied to the `input` element. Deprecated－Use `slotProps.input` instead. This prop will be removed in v7. See Migrating from deprecated APIs for more details.
onChange	func	-	Callback fired when the state is changed. Signature:`function(event: React.ChangeEvent) => void` `event` The event source of the callback. You can pull out the new checked state by accessing `event.target.checked` (boolean).
required	bool	false	If `true`, the `input` element is required.
size	'medium' \| 'small' \| string	'medium'	The size of the component. `small` is equivalent to the dense checkbox styling.
slotProps	{ input?: func \| object, root?: func \| object }	{}	The props used for each slot inside.
slots	{ input?: elementType, root?: elementType }	{}	The components used for each slot inside.
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.
value	any	-	The value of the component. The DOM API casts this to a string. The browser uses "on" as the default value.

The ref is forwarded to the root element.

Inheritance

While not explicitly documented above, the props of the ButtonBase component are also available in Checkbox. You can take advantage of this to target nested components.

Theme default props

You can use MuiCheckbox to change the default props of this component with the theme.

Slots

Slot name	Class name	Default component	Description
root	.MuiCheckbox-root	`SwitchBase`	The component that renders the root slot.
input		`SwitchBase's input`	The component that renders the input slot.

CSS classes

These class names are useful for styling with CSS. They are applied to the component's slots when specific states are triggered.

Class name	Rule name	Description
.Mui-checked		State class applied to the root element if `checked={true}`.
.Mui-disabled		State class applied to the root element if `disabled={true}`.
.MuiCheckbox-colorPrimary	colorPrimary	State class applied to the root element if `color="primary"`.
.MuiCheckbox-colorSecondary	colorSecondary	State class applied to the root element if `color="secondary"`.
.MuiCheckbox-indeterminate	indeterminate	State class applied to the root element if `indeterminate={true}`.
.MuiCheckbox-sizeMedium	sizeMedium	State class applied to the root element if `size="medium"`.
.MuiCheckbox-sizeSmall	sizeSmall	State class applied to the root element if `size="small"`.

You can override the style of the component using one of these customization options:

With a global class name.
With a rule name as part of the component's styleOverrides property in a custom theme.
