The Menu Button is a graphical user interface element that allows users to access a list of options or features within an application or website. Typically represented by three horizontal lines, often referred to as the "hamburger" icon, it provides a compact way to organize navigation links and settings. When clicked, it expands to reveal various choices, making it easier for users to find what they need without cluttering the screen. Menu buttons are commonly found in mobile apps and responsive web designs, where space is limited. They enhance user experience by streamlining navigation and keeping the interface clean. This design element is essential for applications like Facebook, Twitter, and many others, ensuring users can easily explore different sections.
