How to show tabs only when CheckMenuItem is selected

I have this very basic code which will be used to display tabs only when CheckMenuItem is selected:

    CheckMenuItem toolbarSubMenuNavigation = new CheckMenuItem("Navigation");
    toolbarSubMenuNavigation.setOnAction(new EventHandler<ActionEvent>()
    {
        @Override
        public void handle(ActionEvent e)
        {
            // Show or hide tabs
            System.out.println("subsystem1 #1 Enabled!");
        }
    });

This is the code that I want to show or hide when the check box is selected:

TabPane tabPane = new TabPane();

Tab tab0 = new Tab("blue");
tab.setContent(new Rectangle(200,200, Color.BLUE));

Tab tab1 = new Tab("green");
tab.setContent(new Rectangle(200,200, Color.GREEN));

tabPane.getTabs().addAll(tab0, tab1);

Can you tell me how I can show the tabs only when the CheckMenuItem is true? And I want to do this dynamically.

Something like that can work

CheckMenuItem item = new CheckMenuItem();
Tab t = new Tab();
t.getGraphic().visibleProperty().bind(item.selectedProperty());

The item.selectedProperty() is true when is check, and false when it's not, so if you bind it to the visibleProperty() of your node it will visible when item is checked, and not visible when it's not checked
