This is the hidden content that appears when you click the header. You can include any HTML content here - text, images, forms, etc.
This is an expand/collapse widget, also known as an accordion. It allows you to toggle the visibility of content by clicking the header. Multiple widgets can work independently or as part of an accordion group.
The widget uses CSS transitions and JavaScript to smoothly expand and collapse the content. The toggle icon rotates 180 degrees when expanded, providing visual feedback to the user.
