horizontalMenu
The horizontalMenu
component is used to display a horizontal menu with hierarchical drop-down sub-menus.
horizontalMenu
is used in the Main view with top menu template in the View Creation Wizard. If you want to use the new view instead of the existing main view, select the Use as default main view checkbox on the first step of the wizard. Then Studio will replace the layout
attribute of the @Route
annotation in all views and set the new view in the jmix.ui.main-view-id application property.
It can also be used on any view as any other visual component.

Basics
To add the component on a view, place it in the view descriptor:
<horizontalMenu id="horizontalMenu" width="100%"/>
You can also create and add the component to a view in a Java controller:
@Autowired
private UiComponents uiComponents;
@Autowired
private ApplicationContext applicationContext;
@ViewComponent
private VerticalLayout navigation;
@Subscribe
public void onInit(final InitEvent event) {
HorizontalMenu horizontalMenu = uiComponents.create(HorizontalMenu.class);
MenuConfigHorizontalMenuItemProvider itemProvider =
applicationContext.getBean(MenuConfigHorizontalMenuItemProvider.class);
horizontalMenu.setMenuItemProvider(itemProvider);
navigation.add(horizontalMenu);
itemProvider.load();
}

loadMenuConfig
The loadMenuConfig
attribute is used to control the loading of menu structure from Menu Configuration. The default value is true
, which means that the horizontalMenu
component loads its menu structure from MenuConfig
by default. If you want to use a different item provider, you should set the loadMenuConfig
attribute to false
first.
