React Accordion - Keyboard Support
An end user can use the following keys to interact with the UI component.
Key | Action |
---|---|
↑ or PageUp | Sets focus to the previous panel. |
↓ or PageDown | Sets focus to the next panel. |
Home | Sets focus to the first panel. |
End | Sets focus to the last panel. |
Enter | Expands the focused panel. |
Space | Collapses the focused panel. |
You can implement a custom handler for a key using the registerKeyHandler(key, handler) method.
