# toolbarVerticalCompressionBehavior(_:)

Sets how bars should compress when different types of toolbars are hosted together and space is constrained.

## Declaration

```swift
nonisolated func toolbarVerticalCompressionBehavior(_ behavior: ToolbarVerticalCompressionBehavior) -> some View

```

## Discussion

Discussion For example, a productivity-focused app like Files could ensure its toolbar items are preferred over the tab bar: struct ContentView: View {     var body: some View {         TabView {             Tab("Recents") {                 NavigationStack {                     RootView()                         .toolbar {                             Button("Up", systemImage: "chevron.up") {                             }                             Button("Down", systemImage: "chevron.down") {                             }                         }                         .toolbarVerticalCompressionBehavior(.prefersToolbarItems)                 }             }         }     } }
