# scrollTargetBehavior(_:)

Sets the scroll behavior of views scrollable in the provided axes.

## Declaration

```swift
nonisolated func scrollTargetBehavior(_ behavior: some ScrollTargetBehavior) -> some View

```

## Discussion

Discussion A scrollable view calculates where scroll gestures should end using its deceleration rate and the state of its scroll gesture by default. A scroll behavior allows for customizing this logic. You can provide your own ScrollTargetBehavior or use one of the built in behaviors provided by SwiftUI. Paging Behavior SwiftUI offers a PagingScrollTargetBehavior behavior which uses the geometry of the scroll view to decide where to allow scrolls to end. In the following example, every view in the lazy stack is flexible in both directions and the scroll view will settle to container aligned boundaries. ScrollView {     LazyVStack(spacing: 0.0) {         ForEach(items) { item in             FullScreenItem(item)         }     } } .scrollTargetBehavior(.paging) View Aligned Behavior SwiftUI offers a ViewAlignedScrollTargetBehavior scroll behavior that will always settle on the geometry of individual views. ScrollView(.horizontal) {     LazyHStack(spacing: 10.0) {         ForEach(items) { item in             ItemView(item)         }     }     .scrollTargetLayout() } .scrollTargetBehavior(.viewAligned) .safeAreaPadding(.horizontal, 20.0) You configure which views should be used for settling using the scrollTargetLayout(isEnabled:) modifier. Apply this modifier to a layout container like LazyVStack or HStack and each individual view in that layout will be considered for alignment.
