This project showcases a custom expand/collapse component with accessible controls. The button is keyboard navigable and updates its state to reflect the visibility of the content.
The controlled content is hidden by default and becomes visible whenever the associated button is activated.
How does this work? Click the button to toggle the visibility of this content section. The indicator changes to show whether the section is expanded.
Can I add more sections? Yes, duplicate the widget structure and ensure the button and content element IDs are unique.
