# init(_:)

Creates a group box based on a style configuration.

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

## Parameters

`configuration`

The properties of the group box instance being created.

## Discussion

Use this initializer within the [`makeBody(configuration:)`](/documentation/SwiftUI/GroupBoxStyle/makeBody(configuration:))
method of a [`GroupBoxStyle`](/documentation/SwiftUI/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)
    }
}
```
