如何在Vaadin中创建垂直菜单?

对于这种视图,我在MainLayout.java类中有以下代码:

@Theme(value = Lumo.class)
@Route("")
@PWA(name = "Project Base for Vaadin", shortName = "Project Base", enableInstallPrompt = false)
@CssImport("./styles/shared-styles.css")
@CssImport(value = "./styles/menu-buttons.css", themeFor = "vaadin-button")
public class MainLayout extends AppLayout implements RouterLayout {

    public MainLayout() {
        final DrawerToggle drawerToggle = new DrawerToggle();
        drawerToggle.addClassName("menu-toggle");
        addToNavbar(drawerToggle);

        final VerticalLayout top = new VerticalLayout();
        //top.setDefaultVerticalComponentAlignment(Alignment.CENTER);

//        top.setClassName("menu-header");

        final Label title = new Label("Converted Application");
        top.add(title);
        addToNavbar(top);

        top.add(title);
        addToNavbar(top);

        // Navigation items
        addToDrawer(createMenuLink(HomeView.class, HomeView.VIEW_NAME,
                VaadinIcon.EDIT.create()));

        addToDrawer(createMenuLink(MainView.class, MainView.VIEW_NAME,
                VaadinIcon.INFO_CIRCLE.create()));

        addToDrawer(createMenuLink(ConvertedLoginPage.class, ConvertedLoginPage.VIEW_NAME,
                VaadinIcon.LOCK.create()));

        addToDrawer(createMenuLink(Table.class, Table.VIEW_NAME,
                VaadinIcon.LOCK.create()));
    }

    private RouterLink createMenuLink(Class<? extends Component> viewClass, String caption, Icon icon) {
        final RouterLink routerLink = new RouterLink(null, viewClass);
        routerLink.add(icon);
        routerLink.add(new Span(caption));
        icon.setSize("24px");
        return routerLink;
    }
}

你可以创建一个垂直标签栏:

Tabs tabs = new Tabs();
tabs.setOrientation(Tabs.Orientation.VERTICAL);

请在此处找到完整的示例:

英文:

You could create a vertical tab bar:

Tabs tabs = new Tabs();
tabs.setOrientation(Tabs.Orientation.VERTICAL);

Please find my full example here:

你可以将你的RouterLinks添加到一个VerticalLayout中,然后将它添加到抽屉中。

// 导航项目
VerticalLayout routerLinks = new VerticalLayout();

routerLinks.add(createMenuLink(HomeView.class, HomeView.VIEW_NAME, VaadinIcon.EDIT.create()));
routerLinks.add(createMenuLink(MainView.class, MainView.VIEW_NAME, VaadinIcon.INFO_CIRCLE.create()));
routerLinks.add(createMenuLink(ConvertedLoginPage.class, ConvertedLoginPage.VIEW_NAME, VaadinIcon.LOCK.create()));
routerLinks.add(createMenuLink(Table.class, Table.VIEW_NAME, VaadinIcon.LOCK.create()));

addToDrawer(routerLinks);
英文:

You could add your RouterLinks into a VerticalLayout and add that into the drawer.

 // Navigation items
VerticalLayout routerLinks = new VerticalLayout();
routerLinks.add(createMenuLink(HomeView.class, HomeView.VIEW_NAME, VaadinIcon.EDIT.create()));
routerLinks.add(createMenuLink(MainView.class, MainView.VIEW_NAME, VaadinIcon.INFO_CIRCLE.create()));
routerLinks.add(createMenuLink(ConvertedLoginPage.class, ConvertedLoginPage.VIEW_NAME, VaadinIcon.LOCK.create()));
routerLinks.add(createMenuLink(Table.class, Table.VIEW_NAME, VaadinIcon.LOCK.create()));
addToDrawer(routerLinks);
