[en] Navigation Menu Button Example

Hi Team,

The Codepen example (appears after activating the "Open in CodePen" button)
in the following link -
https://www.w3.org/WAI/ARIA/apg/patterns/menu-button/examples/menu-button-links/
is broken and not working as explained.

Please have a look at it and address it at the earliest.

Thanks,
Uday Shetty
