Problem with navigation layout

Hello

I’m trying to do a page with header and menu (left), like the image attachement
The classes i have are:
HEADER (always visible in top of page)

@HtmlImport("styles/shared-styles.html")
@SpringComponent
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class CabeceraView extends HorizontalLayout {
	private ComboBox<String> combo = new ComboBox<>();
	
    public CabeceraView() {
    	
        add(combo);
    }

}

MainView (have header and menu, and the layout where “put” de others views)

@HtmlImport("styles/shared-styles.html")
@Route
@SpringComponent
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class MainView extends VerticalLayout implements RouterLayout{
	
    public MainView() {
    	CabeceraView cabecera = new CabeceraView();
    	HorizontalLayout hl = new HorizontalLayout();
    	MenuView menu = new MenuView();
    	hl.add(menu);
        add(cabecera,menu);
    }

}

The Menu:


@HtmlImport("styles/shared-styles.html")
@Route("menu")
public class MenuView extends HorizontalLayout implements RouterLayout {
	private Button button = new Button();
	private Button button1 = new Button();
    public MenuView() {
    	VerticalLayout vl = new VerticalLayout();
    	
    	button.setText("Hola");
    	button.addClickListener(event->{
    		UI.getCurrent().navigate("hola");
    	});
    	button1.addClickListener(event->{
    		UI.getCurrent().navigate("amigo");
    	});
    	button1.setText("Amigo");
        vl.add(button,button1);
        add(vl);
    }

}

Aand others 2 “views” to try the menu

@HtmlImport("styles/shared-styles.html")
@Route(value = "amigo", layout= MainView.class)
@SpringComponent
@ParentLayout(MenuView.class)
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class AmigoView extends VerticalLayout {
	
    public AmigoView() {
    	Label label = new Label("amigo");
    	
        add(label);
    }

}

@HtmlImport("styles/shared-styles.html")
@Route(value = "hola", layout= MainView.class)
@SpringComponent
@ParentLayout(MenuView.class)
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
public class HolaView extends VerticalLayout {
	
    public HolaView() {
Label label = new Label("hola");
    	
        add(label);
    }

}

My problem is that I have never been able to put HolaView and AmigoView in the layout of the center, I always put down the MainView, and “playing” with Route.layout and ParentLayout the most I have achieved is that it works as I want, but losing the header .

Can someone tell me how is the correct “configuration” to work as I wish?

Thank you very much
