Why it matters
Automatic submissions or navigations when typing or selecting options can cause users to lose work or become disoriented.
Common violations
- Select menus that navigate immediately on change
- Search fields that submit on every keystroke
- Radio buttons that auto-submit forms
- Checkboxes that trigger page reloads
Code examples

Provide explicit submit buttons for form actions. If auto-submission is necessary, warn users in advance with clear instructions.
