InputBase API

API documentation for the React InputBase component. Learn about the available props, and the CSS API.

Import

import InputBase from '@material-ui/core/InputBase';
// or
import { InputBase } from '@material-ui/core';
You can learn about the difference by reading this guide on minimizing bundle size.

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.

Component name

The name MuiInputBase can be used when providing default props or style overrides in the theme.
