The dropdown React Carbon component has been tested against the latest W3C Web Content Accessibility Guidelines (WCAG) 2.1 Level A and AA success criteria and violations have been identified as high priority issues. This document will be updated when these accessibility issues are resolved.

Accessibility considerations

  1. Avoid very long option names to facilitate understandability and perceivability.
  2. Do not use the same word or phrase at the beginning of a set of options.
  3. Avoid options that contain headings and interactive elements such as links, buttons, or checkboxes.
  4. If the dropdown is a required field include the aria-required property and indicate that it is a required field and use the validation message for input errors.


Accessibility testing

Automated, manual and screen reader accessibility verification test has been performed on the dropdown React Carbon Component. WCAG 2.1 Level A and AA success criteria issues have been identified and the list of open accessibility violations is available in the Carbon Component GitHub repository.
