How to Make Website Disclosure Controls Accessible to Keyboard Users

Expandable sections may be clickable with a mouse but not operable or announced correctly from a keyboard. Users can miss hidden details or become unsure which content is open.

What to check

Test tab and activation keys, focus order, expanded state announcements, heading structure, and whether hidden content is removed from keyboard navigation when collapsed.

Recommended next step

Use semantic buttons with clear state and controlled content relationships. Verify the interaction with keyboard and screen reader across multiple expanded sections.
