In WPF the controls Menu and MenuItem inherit from ItemsControl. Based on my understanding, as Prism provides a region adapter for ItemsControls, you could define the Menu (or MenuItem) where you want to add the MenuItems of the modules as a region. Then, you could inject or register a MenuItem in the region (like you would do with a view).

For example, suppose that the shell has a menu which we registered as a region with the name "MenuRegion" and we want to add a MenuItem to the aforementioned menu when a module initializes. This could be achieved doing something like this:

public void Initialize()
    // We create a MenuItem to register in the "MenuRegion."

     MenuItem subItem = new MenuItem();
     subItem.Header = "Click Me";
     subItem.Click += (object sender, RoutedEventArgs e) => { MessageBox.Show("You clicked the \"Click Me\" button."); };
     this.regionManager.RegisterViewWithRegion("MenuRegion", () => subItem);

You can find more information about injecting and registering views in regions in the following chapter of the Prism documentation:

I hope you find this useful,
