include div in foreach just in some condition - php

Question

I have some navbar with menu and submenu, I want to appear some <div> in that menu to appear the submenu just if this menu has submenu items
The div that I want to appear are div1, div2, div3, see comments and in this condition : <?php if ($men["titre"] == $sub["parentmenu"]) : ?>
I can't put them in this foreach : <?php foreach($submenu as $sub) :?> because I need that three div just ones for all the submenu <li>
Exemple of one menu who have submenus:
<li class="Menu1">
<a class="header-menu " href="#">Menu1 title</a> //Menu1
<div class="mobile-header-nav-submenu-container"> //div 1
<ul class="mobile-header-nav-submenu"> //div 2
<div class="mobile-header-nav-submenu-li-container"> //div3
<li class="submenu1">
<a class="" href="#">Submenu1</a>
</li>
<li class="submenu2">
<a class="" href="#">Submenu2</a>
</li>
<li class="submenu3">
<a class="" href="#">Submenu3</a>
</li>
</div>
</ul>
</div>
</li>
My code:
<div class="menu>
<?php foreach ($menu as $men): ?>
<li class="<?php echo $men["titre"]?>">
<a class="header-menu <?php echo $men["lien"]?>" href="<?php if($men["lien"]){echo $baseUrl.$men["lien"];}else{echo '#';}?>"><?php echo $men["titre"]?></a>
<div class="mobile-header-nav-submenu-container"> //div1
<ul class="mobile-header-nav-submenu"> //div2
<div class="mobile-header-nav-submenu-li-container"> //div3
<?php foreach($submenu as $sub) :?>
<?php if ($men["titre"] == $sub["parentmenu"]) : ?>
<li id="<?php echo $sub["titre"]?>" class="mobile-header-nav-submenu-li">
<a class="" href="<?php if($sub["lien"]){echo $baseUrl.$sub["lien"];}else{echo '#';}?>">
<?php echo $sub["titre"]?>
</a>
</li>
<?php endif; ?>
<?php endforeach; ?>
</div>
</ul>
</div>
</li>
<?php endforeach; ?>
</div>
