# init(_:)

Creates a group box based on a style configuration.

## Declaration

```swift
nonisolated init(_ configuration: GroupBoxStyleConfiguration)
```

## Parameters

- `configuration`: The properties of the group box instance being created.

## Discussion

Discussion Use this initializer within the makeBody(configuration:) method of a GroupBoxStyle instance to create a styled group box, with customizations, while preserving its existing style. The following example adds a pink border around the group box, without overriding its current style: struct PinkBorderGroupBoxStyle: GroupBoxStyle {     func makeBody(configuration: Configuration) -> some View {         GroupBox(configuration)             .border(Color.pink)     } }
