如何在顶部显示MenuBar的多个anchorPanes之间切换？

Question

I'm new to JavaFX and I need to switch between multiple Anchor Panes using a MenuBar , so the MenuBar needs to stay on top when I'm switching between these Anchor Panes, I'm using Scene Builder to generate the .FXML files, but have no idea how to do this without creating multiple MenuBars for each Anchor Pane.

My question is how to do this in a simple way? Because I have ready to use Anchor Panes, all I need is a way to share the Menu bar on top of these Anchor panes.

As James Commented, to do this you need to use borderPane with the MenuBar on top of it, and set your Anchor panes inside it using the setCenter() method on the BoderPane , like this:

    @FXML
    private BorderPane borderPane;

    private AnchorPane achor1;
    private AnchorPane achor2;

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        try {
            // TODO
            achor1 = FXMLLoader.load(getClass().getResource(("/Views/anchor1.fxml")));
            achor2 = FXMLLoader.load(getClass().getResource("/Views/anchor2.fxml"));

        } catch (IOException ex) {
            Logger.getLogger(CrechHomeController.class.getName()).log(Level.SEVERE, null, ex);
        }

    }

    @FXML
    public void action1() throws IOException {
        // anchor1

        borderPane.setCenter(achor1);

    }

    @FXML
    public void action2() {
        //anchor2 

        borderPane.setCenter(achor2);
    }
