Creating Lift nested Submenus in different div

Question

I'm trying to build a nested menu structure, but the submenus should appear in a different element on the page.

Grouping and hiding the submenus will make them appear always, not just after activating the parent menu.

Menu.i("Startseite") / "index" >> Hidden >> LocGroup("servicenav"),
    Menu.i("Impressum") / "about"/"index" >> Hidden >> LocGroup("servicenav"),

    Menu.i("menu_1") / "100_menu1" submenus(
        Menu.i("menu_1a") / "100_menu1a" >> Hidden >> LocGroup("sidenavbar"),
        Menu.i("menu_1b") / "200_menu1b" >> Hidden >> LocGroup("sidenavbar"),
        Menu.i("menu_1c") / "300_menu1c" >> Hidden >> LocGroup("sidenavbar")
    ),

    Menu.i("menu_2") / "400_menu2" submenus(
        Menu.i("menu_2a") / "400_menu2a" >> Hidden >> LocGroup("sidenavbar"),
        Menu.i("menu_2b") / "500_menu2b" >> Hidden >> LocGroup("sidenavbar")
    )
)

And the html part:

<ul id="mainnav">
    <lift:Menu.builder li_item:class="open" li_path:class="open">
    Upper Navigation Panel for primary Menu
    </lift:Menu.builder>
 </ul>

---

<ul id="nav">
<lift:Menu.group group="sidenavbar" a:class="firstChild">
    Side-Navigation panel for submenus
<li><menu:bind /></li>
</lift:Menu.group>
</ul>

Has anyone a good idea?

Thanks in advance

Answer 1

So, finally got a solution.

I simlpy added two Sitemaps. The first with with level="0" and expand="false", the second with level="1". However if you click in the second menu, the first will expand regardless of the expand parameter. So I set the in the stylesheet the width and heigth for the following

in the first menu to 0.

Not clean, but it works...

<ul id="mainnav">
    <lift:Menu.builder li_path:class="open" level="0" expand="false">

        Top Menu

    </lift:Menu.builder>
 </ul>

---

<ul id="nav">
    <lift:Menu.builder level="1" li_item:class="current" li_path:class="open">

        Side-menu

    </lift:Menu.builder>
</ul>

ul#mainnav li ul li{
height: 0;
width: 0;
}
