# init(_:selection:rowContent:)

Creates a list that computes its rows on demand from an underlying collection of identifiable data, optionally allowing users to select a single row.

## Declaration

```swift
nonisolated init<Data, RowContent>(_ data: Binding<Data>, selection: Binding<SelectionValue?>?, @ContentBuilder rowContent: @escaping (Binding<Data.Element>) -> RowContent) where Content == ForEach<LazyMapSequence<Data.Indices, (Data.Index, Data.Element.ID)>, Data.Element.ID, RowContent>, Data : MutableCollection, Data : RandomAccessCollection, RowContent : View, Data.Element : Identifiable, Data.Index : Hashable
```

## Parameters

- `data`: The identifiable data for computing the list.
- `selection`: A binding to a selected value.
- `rowContent`: A content builder that creates the view for a single row of the list.
