    $(document).ready(function () {
        $("button[id='columnadd']").click(function () {
            // create the element
            var domElement = $('<div id="shoppingCart' + i++ + '" class="shoppingCart"><h2 class="ui-widget-header">Add Menu Items Here <img src="../Images/delete.png" id="shoppingCart' + z++ + '" style="float: right; cursor:pointer;" onclick="removecolumn(this.id)"/></h2><aside class="ui-widget-content" id="droppable"><ol><li class="placeholder">Add your items here</li></ol></aside></div>');

            $("#columnholder").append(domElement);
            //$(this).after(domElement);

            // at this point we have domElement in our page

            // make it droppable
            domElement.find("ol").droppable({
                activeClass: "ui-state-default",

您可以像这样为丢弃的孩子添加属性

 function makeItDroppableToo(e, ui, obj) {
     $(ui.draggable).attr("parent","MENS");
 }

看看这个JQFAQ.com，它将对 jQuery 开发者很有帮助。
