C# restricting use of a class

The below code does what I would like it to do. The code in the Main method looks and behaves exactly as desired. However, it would be preferable if the class UserMenu, Home and DropdownMenu2 could only be used by the HeaderNavigationMenu to protect other developers from trying to used them outside of the HeaderNavigationMenu class. Additionally most articles frown upon making everything public.

Question: Is the design patter being used below appropriate or is there something better and more acceptable to use in this scenario?

public class HeaderNavigationMenu
{
    public HeaderNavigationMenu()
    {
        UsersMenu = new UsersMenu();
        Home = new Home();
        DropdownMenu2 = new DropdownMenu2();
    }

    public UsersMenu UsersMenu { get; set; }
    public Home Home { get; set; }
    public DropdownMenu2 DropdownMenu2 { get; set; }
}

public class UsersMenu
{
  ...
}

public class Home
{
  ...
}

public class DropdownMenu2
{
  public void SelectOption3()
  {
    ...
  }
  ...
}

static void Main(string[] args)
{
  HeaderNavigationMenu navigationMenu = new HeaderNavigationMenu();
  navigationMenu.DropdownMenu2.SelectOption3();

  // The following code is an example of undesired capability; 
  // prefer if Home class could only be 
  // used by HeaderNavigationMenu class
  Home home = new Home();
}
