# selectionBackgroundStyle

The style applied to the background of selected items.

## Declaration

```swift
var selectionBackgroundStyle: NSScrubberSelectionStyle? { get set }
```

## Discussion

Discussion The default value is nil, which specifies no background decoration. You can either choose from one of the built-in selection styles (outlineOverlay or roundedBackground), or you can subclass NSScrubberSelectionStyle to create your own custom selection style.
