Update Menu.php

[Elberius]

The last commit makes the menu's HTML invalid. In libraries/astroid/framework/library/astroid/Component/Menu.php at 124, I guess it meant to be:

// The next item is shallower.
elseif ($item->shallower) {
    echo '</li>';
    if ($item->level == 1 && $item->parent) {
        echo str_repeat('</ul>' . '</li>', $item->level_diff);
    } else {
        echo str_repeat('</ul></div>' . '</li>', $item->level_diff);
    }
}
