jQuery toggle class on sub element of li - not working - html

Question

So I have multiple LI's like below as it's a menu and I am trying to create a drop-down but for some reason, my jQuery code is not working. Can someone help me?
FYI I can't change HTML as it's dynamically generating in Shopify. I can only change jQuery and CSS
<li class="grid__item lvl-1 ">
<a class="site-nav lvl-1 light-body">Furry Artist</a>
<ul class="subLinks inactive">
<li class="lvl-2">
Erdbeer Joghurt
</li>
<li class="lvl-2">
Jeson RC
</li>
</ul>
</li>
$( document ).ready(function() {
$("ul.subLinks").addClass("inactive");
});
$('a.site-nav.lvl-1').click(function() {
$(this).find("ul.subLinks").toggleClass('active-drop-down');
});
.inactive {
display:none;
}
.active-drop-down {
display:block !important;
}

Your issue is $(this).find... in the a click handler - at this point, this is the a.
.find() looks at the selectors children - but the menu is not a child of the a, it's a sibling.
Change to
$(this).closest("li").find("ul.subLinks"...
(maybe $(this).next().toggleClass... with a caveat on .this() that it's always the very next element).
Updated snippet:
$('a.site-nav.lvl-1').click(function() {
$(this).closest("li").find("ul.subLinks").toggleClass('active-drop-down');
});
.inactive {
display:none;
}
.active-drop-down {
display:block !important;
}
