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 here: https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#autofill

CSS API

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}.
inputType Styles applied to the input element if type is not "text"`.
inputTypeSearch Styles applied to the input element if type="search".

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

If using the overrides key of the theme as documented here, 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.
