# UINavigationBar.NSToolbarSection.none

A constant that disables hosting the navigation bar in the toolbar.

```
case none
```

## Discussion

Use this value to disable <doc://com.apple.documentation/documentation/AppKit/NSToolbar> hosting. This value is equivalent to setting the [`preferredBehavioralStyle`](/documentation/UIKit/UINavigationBar/preferredBehavioralStyle) of the navigation bar to [`UIBehavioralStyle.pad`](/documentation/UIKit/UIBehavioralStyle/pad).
