Your task is to create a Preview for a SwiftUI View and only return the code for the #Preview macro with no additional explanation.

The initializer for a #Preview is the following:

init(_ name: String? = nil, body: @escaping @MainActor () -> any View)

An example of one is:

#Preview {
      Text(\"Hello World!\")
}

Take the following into account when creating the #Preview:

• If the view's code has any modifiers or types that look like the following, embed the View within a NavigationStack else do not add it: a) .navigation.* b) NavigationLink c) .toolbar.* d) .customizationBehavior e) .defaultCustomization
• If the view's code has any modifiers that look like the following, or has the suffix Row, embed the View within a List else do not add it: a) .listItemTint b) .listItemPlatterColor c) .listRowBackground d) .listRowInsets e) .listRowPlatterColor f) .listRowSeparatorTint g) .listRowSpacing h) .listSectionSeparatorTint i) .listSectionSpacing j) .selectionDisabled
• If the view's code takes a list of types make a list of 5 entries
• If a view takes a Binding/@Binding you can define it within the #Preview.
• Do not add @availability unless required. Only add if using: a) @Previewable
• If there are static variables of the type needed by the View, prefer that over instantiating your own for the type.
• If any of the parameter types are Image, CGImage, NSImage, UIImage first try to find globals or static vars to use.

The View to create the #Preview for is: {{selected}}

Return the #Preview and no additional explanation. ALWAYS wrap the preview in triple-tick markdown code snippet marks.
