Props

Props of the InputBase component are also available.

Name	Type	Default	Description
autoComplete	string	-	This prop helps users to fill forms faster, especially on mobile devices. The name can be confusing, as it's more like an autofill. You can learn more about it following the specification.
autoFocus	bool	-	If `true`, the `input` element is focused during the first mount.
classes	object	-	Override or extend the styles applied to the component. See CSS classes API below for more details.
color	'primary' \| 'secondary' \| string	-	The color of the component. It supports both default and custom theme colors, which can be added as shown in the palette customization guide. The prop defaults to the value (`'primary'`) inherited from the parent FormControl component.
components	{ Input?: elementType, Root?: elementType }	{}	The components used for each slot inside. Deprecated－use the `slots` prop instead. This prop will be removed in v7. See Migrating from deprecated APIs for more details.
componentsProps	{ input?: object, root?: object }	{}	The extra props for the slot components. You can override the existing props or add new ones. Deprecated－use the `slotProps` prop instead. This prop will be removed in v7. See Migrating from deprecated APIs for more details.
defaultValue	any	-	The default value. Use when the component is not controlled.
disabled	bool	-	If `true`, the component is disabled. The prop defaults to the value (`false`) inherited from the parent FormControl component.
disableUnderline	bool	false	If `true`, the `input` will not have an underline.
endAdornment	node	-	End `InputAdornment` for this component.
error	bool	-	If `true`, the `input` will indicate an error. The prop defaults to the value (`false`) inherited from the parent FormControl component.
fullWidth	bool	false	If `true`, the `input` will take up the full width of its container.

inputComponent	elementType	'input'	The component used for the `input` element. Either a string to use a HTML element or a component.
inputProps	object	{}	Attributes applied to the `input` element.
inputRef	ref	-	Pass a ref to the `input` element.
margin	'dense' \| 'none'	-	If `dense`, will adjust vertical spacing. This is normally obtained via context from FormControl. The prop defaults to the value (`'none'`) inherited from the parent FormControl component.

minRows	number \| string	-	Minimum number of rows to display when multiline option is set to true.
multiline	bool	false	If `true`, a TextareaAutosize element is rendered.
name	string	-	Name attribute of the `input` element.
onChange	func	-	Callback fired when the value is changed. Signature:`function(event: React.ChangeEvent) => void` `event` The event source of the callback. You can pull out the new value by accessing `event.target.value` (string).

readOnly	bool	-	It prevents the user from changing the value of the field (not from interacting with the field).

rows	number \| string	-	Number of rows to display when multiline option is set to true.
slotProps	{ input?: object, root?: object }	{}	The extra props for the slot components. You can override the existing props or add new ones. This prop is an alias for the `componentsProps` prop, which will be deprecated in the future.

startAdornment	node	-	Start `InputAdornment` for this component.
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.
