# usingFocus(identifier:shouldCacheItems:)

## Declaration

```swift
class func usingFocus(identifier: UIDeferredMenuElement.Identifier, shouldCacheItems: Bool) -> Self
```

## Parameters

- `identifier`: An identifier for this deferred element that responders can check to determine which elements to provide.
- `shouldCacheItems`: Whether or not the deferred element caches items. Passing in @c YES causes this deferred element to ask the responder chain for elements only once, when the element is first encountered in a menu. Passing in @c NO asks the responder chain for elements every time the element is displayed.

## Discussion

Discussion Returns a placeholder menu element that is replaced with elements provided from the responder chain. A loading UI takes the place of the element in the menu until it is fulfilled. The element may be stored and re-used across menus.
