Pop-up buttons

Pop-up buttons present a list of mutually exclusive options. After selecting an item from the menu, the button updates to show the current choice, helping users track their selection. Common examples include choosing text size in Settings, selecting video quality in media players, or picking time zones.

HIG specifies key patterns for pop-up buttons:

• Menu content. Options should be mutually exclusive and presented in a flat list. For example, meeting admission options: People who were invited, Everyone, Only me
• Default selection. The button shows a useful default option before users make their first choice. For instance, Sidebar icon size defaults to Medium
• Clear labeling. Button labels or nearby text should help users predict available options without opening the menu^[1]
