# supportsGrouping

A Boolean value that indicates whether to group the device with others in the AirPlay UI.

## Declaration

```swift
var supportsGrouping: Bool { get set }
```

## Discussion

Discussion This property provides a convenient way to send the same media stream to multiple devices and list them as a group in the AirPlay UI (AVRoutePickerView). For example, a set of speakers arranged around the room can implement stereo playback by each playing different audio channels from an audio stream. When someone selects a media receiver in the AirPlay menu, the system checks if it supports grouping. If so, the AirPlay UI displays a checkbox next to any other media receivers that also support grouping and implement the same protocol (DDDevice.Protocol). If a person selects multiple devices in the menu, the selected devices reorder next to each other in the list. note: Implement didReceiveEvent(_:) in the DDDiscoveryExtension to detect when a person changes the device grouping using the AirPlay UI.
