在foreach的Joomla 3菜单php找到第二个li子菜单

in Joomla menu module php - default.php,How can i find the second li submenu and add class name 'the-secondsubmenu' into it?

the output will looks like this:

<ul class="nav"> 
    <li>

            <a></a> 
            <ul>
                <li class="the-secondsubmenu">
                    <a></a>
                </li>
            </ul> 

    </li>
</ul>

i'm add this line in foreach

if($item->level < 2): $counter += count($item); endif;

and add these

if ($item->deeper)
{
    $class .= ' deeper';
}
elseif($item->deeper && $counter === 2){

    $class .= ' deeper the-secondsubmenu';
}

THE PHP

foreach ($list as $i => &$item)
{
    if($item->level < 2):
        $counter += count($item);
    endif;

    $class = 'item-' . $item->id;

    if (($item->id == $active_id) OR ($item->type == 'alias' AND $item->params->get('aliasoptions') == $active_id))
    {
        $class .= ' current';
    }

    if (in_array($item->id, $path))
    {
        $class .= ' active';
    }
    elseif ($item->type == 'alias')
    {
        $aliasToId = $item->params->get('aliasoptions');

        if (count($path) > 0 && $aliasToId == $path[count($path) - 1])
        {
            $class .= ' active';
        }
        elseif (in_array($aliasToId, $path))
        {
            $class .= ' alias-parent-active';
        }
    }

    if ($item->type == 'separator')
    {
        $class .= ' divider';
    }


    if ($item->deeper)
    {
        $class .= ' deeper';
    }
    elseif($item->deeper && $counter === 0){

        $class .= ' deeper the-secondsubmenu';
    }

these code not working,
As always, your assistance is appreciated!

if you write this code, the second part won't be executed because the test includes the same test as the first block.

if ($item->deeper) {
    $class .= ' deeper';
}
elseif ($item->deeper && $counter === 2) {
    $class .= ' deeper the-secondsubmenu';
}

maybe you should try to put the second block first :

if ($item->deeper && $counter === 2) {
    $class .= ' deeper the-secondsubmenu';
}
elseif ($item->deeper) {
    $class .= ' deeper';
}
