An expand/collapse widget is a user interface component that allows users to show or hide content with a simple click or tap. This design pattern is commonly used to organize information efficiently and reduce visual clutter on a page.
It's particularly useful for FAQs, navigation menus, and content-heavy pages where users need to focus on specific sections at a time.
The expand/collapse widget works through a combination of HTML structure, CSS styling, and JavaScript functionality:
HTML: Uses semantic markup with buttons and content containers.
CSS: Employs transitions for smooth animations, controlling max-height and overflow properties.
JavaScript: Toggles classes to trigger the expand/collapse behavior.
This approach ensures a smooth user experience with minimal performance impact.
