# otherItemsProxy

The identifier of the special “other items proxy”, which is used to nest bars up the responder chain.

```
static let otherItemsProxy: NSTouchBarItem.Identifier
```

## Discussion

Use this identifier in the [`itemIdentifiers`](/documentation/AppKit/NSTouchBar/itemIdentifiers) array of an [`NSTouchBar`](/documentation/AppKit/NSTouchBar) object, and a special proxy item will be instantiated for you.

When the [`NSTouchBar`](/documentation/AppKit/NSTouchBar) containing this item is visible, bars provided by objects closer to the first responder will be nested inside the space denoted for this item.Note that a touch bar lacking this item identifier will be replaced in its entirety by touch bars closer to the first responder in the responder chain.
