What does the term 'Hamburger Menu' refer to in UI design?

The term 'Hamburger Menu' refers to a navigation icon formed by three horizontal lines stacked on top of each other, resembling a hamburger. This design element is widely utilized in user interface design to indicate that tapping on the icon will reveal a menu containing additional navigation options or features. The hamburger menu allows for a compact navigation solution, enabling designers to conserve screen space, particularly on mobile devices, while still providing access to various sections of an application or website.

This design choice helps streamline the user experience by keeping the interface clean and uncluttered. When users interact with the hamburger menu icon, they are presented with further choices, allowing them to navigate through the application without overwhelming the screen with too many options at once.
