I have list of items :

<ul class="list 32" data-id="1"><li class="item" data-id="1">1</li><li class="item" data-id="1">2</li></ul>

and this js code with sortable

$(".drop").sortable({
            receive: function (e, ui) {
                var identicalItemCount  = $(".list."+id+"").children('li:contains(???)').length;
          
                console.log(ui.item.text())
                if (identicalItemCount > 1) {
                  console.log("this) } else { console.log("this)});

My goal is to archive is this: If the data-id exist, it shouldn't be droppable?
