# CPMessageListItemTrailingConfiguration

An object that describes the appearance of a message list item’s trailing region.

## Declaration

```swift
class CPMessageListItemTrailingConfiguration
```

## Overview

Overview Use a trailing configuration to describe the visual elements that a message list item’s trailing region contains. The region can show a CPMessageTrailingItem and an image. Configurations are immutable. To modify the list item’s trailing configuration, update its trailingConfiguration property with a new configuration. CarPlay detects the change and redraws the message list item.
