Smarty Menus

Menu arranged as such

$menus = array(
    'menu-id-1': (item1, item2, item3, item4....),
    'menu-id-2': (.....)
);

Each menu item has a submenu ID that can be matched to the $menus array.

Will this template generate the right menu hierarchy?

{* Must use global menus variable to determine hierarchy. *}
{function name=menu}
    <ul>
    {foreach $data as $m}
        <li>
            {$m}
            {if is_array($menus[$m@key])}
                {menu data=$menus[$m@key]}
            {/if}
        </li>
    {/foreach}
    </ul>
