# extraProminentInsetGroupedHeader()

Creates the default configuration you use to style an extra prominent header in an inset grouped list.

```
static func extraProminentInsetGroupedHeader() -> UIListContentConfiguration
```

## Return Value

The default configuration for an extra prominent header in an inset grouped list.

## Discussion

Create this configuration to update the content and styling of a header in a table view or collection view list.

For an appearance consistent with system defaults, display your header in a table view or collection view list that you configure with one of the following enumeration cases:

- [`UITableView.Style.insetGrouped`](/documentation/UIKit/UITableView/Style-swift.enum/insetGrouped)
- [`UICollectionLayoutListConfiguration.Appearance.insetGrouped`](/documentation/UIKit/UICollectionLayoutListConfiguration-swift.struct/Appearance-swift.enum/insetGrouped)

Configure the background of your header using one of the [`UIBackgroundConfiguration`](/documentation/UIKit/UIBackgroundConfiguration-swift.struct) options below. Match the background of your header to the corresponding table view or collection view styles as follows:

|Background configuration option                                                                               |Matching table view or collection view styles                                                                                                                                                                             |
