Search menus are specifically designed for handling long lists, such as a list of countries or languages. They improve user experience by incorporating features like auto-suggest or auto-complete, which dynamically filter results as users type in their query.

By integrating a search function into a lengthy menu, you're essentially streamlining the navigation process. Users can quickly locate their desired option without endlessly scrolling through a list. This functionality not only saves time but also reduces cognitive load, making it easier for users to complete their tasks.
