# NSButton.ButtonType.radio

A button that displays a single selected value from group of possible choices.

## Declaration

```swift
case radio
```

## Discussion

Discussion A radio button is similar to a NSButton.ButtonType.switch button, but it constrains the selection to a single button within a group. Radio buttons are ideal for choosing one value from a small number of options. This option corresponds to the Radio type in Interface Builder’s Attributes Inspector.
