Bug

https://material-ui.com/components/autocomplete/#react-select

this tutorial contains errors. Open the sandbox and click on a element in the list.

The following is logged to the console:

Warning: Failed prop type: The prop `innerProps.key` is marked as required in `Option`, but its value is `undefined`.
Warning: Failed prop type: The prop `innerRef` is marked as required in `Option`, but its value is `undefined`.

Tested on Linux in Chrome and Firefox

Thank you for raising this issue. I can confirm the bug.

I'd also like to note that react-select is still using cWRP. While the warning will be fixed once JedWatson/react-select#3716 is released it's still using those unsafe lifecycle methods. Just writing this down as a mental note that this demo will cause issues in concurrent mode.

If you comment out those PropTypes in SingleValue. and Option.propTypes errors disappear and everything seems to be working as expected. Is there any actual need for those?

See #13863, we will remove these 3 integration examples in favor of a single, ready to use one.
