A user interface element presenting a linear set of mutually exclusive options. Selecting one option automatically deselects the others. This control allows users to quickly switch between different views or modes within an application. For instance, consider an email application utilizing this element to let users filter between “Inbox,” “Sent,” and “Drafts” views.
Its implementation offers several advantages. It simplifies navigation by providing a clear and intuitive way for users to change the displayed content. It enhances the user experience by grouping related functionalities and making them easily accessible. Historically, this type of control evolved from tabbed interfaces, offering a more compact and mobile-friendly alternative.
