CircularProgress API

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

Import

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

ARIA

If the progress bar is describing the loading progress of a particular region of a page, you should use aria-describedby to point to the progress bar, and set the aria-busy attribute to true on that region until it has finished loading.
