# UICollectionLayoutListConfiguration.FooterMode.supplementary

A footer mode that uses supplementary views to show footers.

## Declaration

```swift
case supplementary
```

## Discussion

Discussion Choose this footer mode to use supplementary views with elementKindSectionFooter as the section footer. By default, lists that use the UICollectionLayoutListConfiguration.Appearance.plain and UICollectionLayoutListConfiguration.Appearance.sidebarPlain list appearances use pinned footers. You must use this footer mode if you want to opt into this default pinning behavior.
