# UISplitViewController.DisplayMode.oneBesideSecondary

One sidebar appears side-by-side with the secondary view controller.

```
case oneBesideSecondary
```

## Discussion

This display mode shows one sidebar tiled next to the secondary view controller. The sidebar shown is the primary column for [`UISplitViewController.Style.doubleColumn`](/documentation/UIKit/UISplitViewController/Style-swift.enum/doubleColumn) interfaces and the supplementary column for [`UISplitViewController.Style.tripleColumn`](/documentation/UIKit/UISplitViewController/Style-swift.enum/tripleColumn) interfaces. The sidebar is displayed on the side specified by [`primaryEdge`](/documentation/UIKit/UISplitViewController/primaryEdge-swift.property), followed by the secondary view controller. The secondary view controller’s view is fully interactive.

This display mode is available for the [`UISplitViewController.SplitBehavior.tile`](/documentation/UIKit/UISplitViewController/SplitBehavior-swift.enum/tile) and [`UISplitViewController.SplitBehavior.displace`](/documentation/UIKit/UISplitViewController/SplitBehavior-swift.enum/displace) split behaviors.
