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.

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.
className	string		The CSS class name of the wrapper element.
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 native input. Either a string to use a DOM 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.
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	string \| number		Number of rows to display when multiline option is set to true.
rowsMax	string \| number		Maximum 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.
