        $menu = Menu::create(array(
            'class' => 'sidebar-menu',
            'data-widget' => 'tree'
        ))
        // ->add(label, url, icon, submenu, li_class)
        ->add('Master Data', null, null, null, 'header')
        ->add('Dashboard', '#', 'fa fa-dashboard',
            // submenu
            Menu::create(array(
                'class' => 'treeview-menu'
            ))
            ->add('Create', '/create', 'fa fa-plus')
            ->add('List', '/list', 'fa fa-list')
        , 'treeview')
        ->add('Jenis Kecerdasan', '/jenis-kecerdasan', 'fa fa-lightbulb-o')
        ->add('Kuisioner', '/kuisionair', 'fa fa-edit')
        ->add('Siswa', '/siswa', 'fa fa-users')
        ->add('Tes Kecerdasan', null, null, null, 'header')
        ->add('Tes Baru', '/new-test', 'fa fa-plus')
        ->add('Report', '/report', 'fa fa-file')
        ->render();

        echo $menu;
    ?>
</div>

<ul class="sidebar-menu" data-widget="tree">
    <li class="header">Master Data</li>
    <li class="treeview">
        <a href="#"><i class="fa fa-dashboard"></i>Dashboard<i class="fa fa-angle-left pull-right"></i></a>
        <ul class="treeview-menu">
            <li><a href="/create"><i class="fa fa-plus"></i>Create</a></li>
            <li><a href="/list"><i class="fa fa-list"></i>List</a></li>
        </ul>
    </li>
    <li><a href="/jenis-kecerdasan"><i class="fa fa-lightbulb-o"></i>Jenis Kecerdasan</a></li>
    <li><a href="/kuisionair"><i class="fa fa-edit"></i>Kuisioner</a></li>
    <li><a href="/siswa"><i class="fa fa-users"></i>Siswa</a></li>
    <li class="header">Tes Kecerdasan</li>
    <li><a href="/new-test"><i class="fa fa-plus"></i>Tes Baru</a></li>
