InputBase API

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

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

InputBase contains as few styles as possible. It aims to be a simple building block for creating an input. It contains a load of style reset and some state logic.

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.
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 DOM element or a component.
inputProps	object	{}	Attributes applied to the `input` element.
inputRef	func \| object		This prop can be used to pass a ref callback 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`.
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.
select	bool	false	Should be `true` when the component hosts a select.
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 (native element).
