Knowledge Base & Operational DocumentationHow to Make Website Expandable Sections Work With Screen Readers
11/10/2026
Expandable panels need clear control labels and state announcements so users know when content is available.
Checks to make
Use a button with an accessible name and expanded state, connect it to the controlled content, and preserve keyboard operation. Test multiple panels, focus order, and screen reader announcements when sections open and close.
When to get help
Accessibility review can assess disclosure controls and content structure. Informatix Systems can assess the symptoms, evidence, and next steps. Contact Informatix Systems to discuss this issue.
