# NSCollectionLayoutGroupCustomItem

An item used in a group with a custom layout arrangement.

## Declaration

```swift
@MainActor class NSCollectionLayoutGroupCustomItem
```

## Overview

Overview You use a custom item if you want to specify a layout with a custom arrangement, like a radial or diagonal layout. You use custom items within a group that’s created with custom(layoutSize:itemProvider:). Instead of providing a layout size for the custom item, like you do when you create an NSCollectionLayoutItem, you provide a frame instead.
