# collectionView(_:contextMenuConfiguration:highlightPreviewForItemAt:)

Asks the delegate for a preview of the item at the specified index path when a context-menu interaction begins.

```
optional func collectionView(_ collectionView: UICollectionView, contextMenuConfiguration configuration: UIContextMenuConfiguration, highlightPreviewForItemAt indexPath: IndexPath) -> UITargetedPreview?
```

## Parameters

`collectionView`

The collection view containing the item.

`configuration`

The configuration of the menu to present if the interaction proceeds.

`indexPath`

The index path of the item where the interaction occurs.

## Return Value

A targeted preview object corresponding to the item at the index path to use during the menu’s highlight and presentation animation.

## Discussion

The system calls this method when a context-menu interaction begins. Implement this method to override the default highlight preview that the collection view generates for the item at `indexPath`.
