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';

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.

fullWidth bool false If true, the input will take up the full width of its container.
