Accessibility Impacts

Please note that changing the tabindex has accessibility implications. You can unintentionally upset the logical tabindex order determined by the browser when the page is loaded which can affect usability.

If your goal is to meet required accessibility guidelines, we highly discourage the use of this filter and recommend letting the user’s browser determine the tabindex of your page.
