How to move only particular item using drag and drop JQuery?

I don't want to move all the item to the div. I wants to move only specific item form one div to another

<ul id="sortable1" class="connectedSortable">
  <li class="ui-state-default">StoreID</li>    // I want to move only this STOREID li element to another UL
  <li class="ui-state-default">ItemLookupCode</li>
  <li class="ui-state-default">ExtendedCost</li>
  <li class="ui-state-default">Quantity</li>
  <li class="ui-state-default">Price</li>
</ul>

<ul id="sortable2" class="connectedSortable">

</ul>


</body>
</html>

I want to move only the first element of UL StoreID to another UL nor all the elements. How to achieve it.

Thanks

Solution

  • This is best done using update or receive callbacks. The key is: ui.sender.sortable("cancel"); This will revert the change.

    Working Example: https://jsfiddle.net/Twisty/4f5yh3pa/

    HTML

    <ul id="sortable1" class="connectedSortable">
  <li class="ui-state-default acceptable">StoreID</li>
  <li class="ui-state-default">ItemLookupCode</li>
  <li class="ui-state-default">ExtendedCost</li>
  <li class="ui-state-default">Quantity</li>
  <li class="ui-state-default">Price</li>
</ul>

<ul id="sortable2" class="connectedSortable">
</ul>

    CSS

    .connectedSortable {
  border: 1px solid #eee;
  width: 142px;
  min-height: 20px;
  list-style-type: none;
  margin: 0;
  padding: 5px 0 0 0;
  float: left;
  margin-right: 10px;
}

#sortable1 {
  background: #fff;
}

#sortable2 {
  background: #999;
}

.connectedSortable li {
  margin: 0 5px 5px 5px;
  padding: 5px;
  font-size: 1.2em;
  width: 120px;
}

    JavaScript

    $(function() {
  $(".connectedSortable").sortable({
    connectWith: ".connectedSortable",
    update: function(e, ui) {
      if ($(e.target).attr("id") == "sortable2") {
        if (ui.item.hasClass("acceptable")) {
          console.log($(this).attr("id") + " accepted item: ", ui.item);
        } else {
          console.log($(this).attr("id") + " rejected item: ", ui.item);
          ui.sender.sortable("cancel");
        }
      }
    }
  }).disableSelection();
});

    You can animate this if you want to make it look more like draggable.
