Collapsible groups in Google Sites are a great way to organize content and make your pages cleaner and more interactive. These expandable sections allow you to hide large amounts of text or media under clickable headings, helping visitors focus on key points without feeling overwhelmed.
You can add a collapsible text box by going to the "Insert" panel and selecting "Collapsible text".
