InputBase API

API reference docs for the React InputBase component. Learn about the props, CSS, and other APIs of this exported module.

Demos

For examples and details on the usage of this React component, visit the component demo pages:

Import

import InputBase from '@mui/material/InputBase';
// or
import { InputBase } from '@mui/material';
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.
