in a book club app I’m trying to write, I have a NavigationSplitView which displays a list of readers in a selectable List that gives the user access to each reader’s comments on a given book. Above the list of readers is a home button “Book” that takes the user back to the book’s main page:

struct ProjectView: View
{
    @State private var readers: [Reader]
    
    init(readers: [Reader])
    {
        self.readers = readers
    }
    
    var body: some View
    {
        NavigationSplitView
        {
                List(selection: self.$selectedReader)
                {
                    Button("Book")
                    {
                        self.selectedReader = nil
                    }
                    
                    Divider()
                                        
                    ForEach (self.readers, id: .self)
                    {
                        reader in Text(reader.name)
                    }
                }
        }
        detail:
        {
            if let selectedReader = self.selectedReader
            {
                ReaderView(reader: selectedReader)
            }
            else
            {
                BookView()
            }
        }
        #if os(macOS)
        .navigationSplitViewColumnWidth(min: 180, ideal: 200)
        #endif
        .navigationTitle(self.project.name)
    }
}

I’m trying to make it so that “Book” will select just as the reader names in the reader list do, you can see what I mean in this video:

Does anyone know how to accomplish this? Or is it even possible?
