Input API

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

import Input from '@material-ui/core/Input';

Props

Name Type Default Description
autoComplete string This property 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.

disabled bool If true, the input element will be disabled.
disableUnderline bool If true, the input will not have an underline.

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.

Signature:
function(event: object) => void
event: The event source of the callback. You can pull out the new value by accessing event.target.value.
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 union: string |

The ref is forwarded to the root element.

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

CSS

You can override all the class names injected by Material-UI thanks to the classes property. This property accepts the following keys:

Name Description
root Styles applied to the root element.
formControl Styles applied to the root element if the component is a descendant of FormControl.
focused Styles applied to the root element if the component is focused.
disabled Styles applied to the root element if disabled={true}.
underline Styles applied to the root element if disableUnderline={false}.
error Styles applied to the root element if error={true}.
multiline Styles applied to the root element if multiline={true}.
fullWidth Styles applied to the root element if fullWidth={true}.
input Styles applied to the input element.
inputMarginDense Styles applied to the input element if margin="dense".
inputMultiline Styles applied to the input element if multiline={true}.
inputTypeSearch Styles applied to the input element if type="search".

Have a look at the overriding styles with classes section and the implementation of the component for more detail.

If using the overrides key of the theme, you need to use the following style sheet name: MuiInput.

Inheritance

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

Notes

The component is fully StrictMode compatible.
