Can AccessBell Test This Automatically?

Not fully. Like most WCAG criteria that depend on meaning or context, this one needs a person to judge. AccessBell's report lists it for manual review rather than marking it pass or fail automatically, so it never gets missed.

How to Test It by Hand

Change the value of each dropdown, radio button and checkbox and confirm nothing unexpected happens without a clear warning first.

Common Failures

  • Selecting a dropdown option immediately navigates to a new page with no warning or explicit submit action.
