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'

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).

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.
