Input API

The API documentation of the Input React component. Learn more about the props and the CSS customization points.

Import

import Input from '@material-ui/core/Input';
// or
import { Input } from '@material-ui/core';

You can learn more about the difference by reading this guide.

Component name

The MuiInput name can be used for providing default props or style overrides at the theme level.

Props

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 will be 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'		The color of the component. It supports those theme colors that make sense for this component.
defaultValue	any		The default input element value. Use when the component is not controlled.
disabled	bool		If true, the input element will be disabled.
disableUnderline	bool		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. This is normally obtained via context from FormControl.
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	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.
maxRows	number | string		Maximum number of rows to display when multiline option is set to true.
multiline	bool	false	If true, a textarea element will be rendered.
name	string		Name attribute of the input element.
onChange	func		Callback fired when the value is changed. Signature: function(event: object) => void event: The event source of the callback. You can pull out the new value by accessing event.target.value (string).
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 will be required.
rows	number | string		Number of rows to display when multiline option is set to true.
startAdornment	node		Start InputAdornment for this component.
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.

Any other props supplied will be provided to the root element (InputBase).

You can override the style of the component thanks to one of these customization points:

• With a rule name of the classes object prop.
• With a global class name.
• With a theme and an overrides property.

If that's not sufficient, you can check the implementation of the component for more detail.

Inheritance

The props of the InputBase component are also available. You can take advantage of this behavior to target nested components.
