Success Criterion 3.2.2 — Level A

Quick Answer

Changing the value of a UI component must not automatically trigger a context change.

Why It Matters

Select dropdowns that auto-navigate when changed are inaccessible to keyboard and screen reader users.

How to Audit

Run an automated accessibility scan to detect common On Input failures. Then manually verify with: keyboard-only navigation, a screen reader (VoiceOver on Mac, NVDA on Windows), and browser developer tools. Automated tools catch approximately 40% of On Input issues — manual testing is essential.

How to Fix

Add an explicit 'Go' button for any navigation triggered by input. Don't auto-submit on change.
