Component demos

For examples and details on the usage of this React component, visit the component demo pages:

Text Field

Import

import InputBase from '@mui/material/InputBase';
// or
import { InputBase } from '@mui/material';

Learn about the difference by reading this guide on minimizing bundle size.

InputBase contains as few styles as possible. It aims to be a simple building block for creating an input. It contains a load of style reset and some state logic.

Props

Props of the native 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 API below for more details.
color	'primary' \| 'secondary' \| 'error' \| 'info' \| 'success' \| 'warning' \| 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. This prop is an alias for the `slots` prop. It's recommended to use the `slots` prop instead.
componentsProps	{ 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 `slotProps` prop. It's recommended to use the `slotProps` prop instead, as `componentsProps` will be deprecated in the future.
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.
disableInjectingGlobalStyles	bool	false	If `true`, GlobalStyles for the auto-fill keyframes will not be injected/removed on mount/unmount. Make sure to inject them at the top of your application. This option is intended to help with boosting the initial rendering performance if you are loading a big amount of Input components at once.
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.
id	string		The id of the `input` element.
inputComponent	element type	'input'	The component used for the `input` element. Either a string to use a HTML element or a component. This needs to be able to hold a ref.
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.
maxRows	number \| string		Maximum number of rows to display when multiline option is set to true.
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.
onBlur	func		Callback fired when the `input` is blurred. Notice that the first argument (event) might be undefined.
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).
onInvalid	func		Callback fired when the `input` doesn't satisfy its constraints.
placeholder	string		The short hint displayed in the `input` before the user enters a value.
readOnly	bool		It prevents the user from changing the value of the field (not from interacting with the field).
required	bool		If `true`, the `input` element is required. The prop defaults to the value (`false`) inherited from the parent FormControl component.
rows	number \| string		Number of rows to display when multiline option is set to true.
size	'medium' \| 'small' \| string		The size of the component.
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.
slots	{ input?: elementType, root?: elementType }	{}	The components used for each slot inside. This prop is an alias for the `components` 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.
type	string	'text'	Type of the `input` element. It should be a valid HTML5 input type.
value	any		The value of the `input` element, required for a controlled component.

The ref is forwarded to the root element.
