+
+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:
+```swift
+#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.
