Nested drag and drop using jquery ui

Question

To Drop items into dropped items

<table id='list1' >
</table>

<ul id="list2" >
</ul>

<table id='list3' >
<tr><td>test<ul style="min-height: 100px;border:1px solid red" class="drop-container"></ul></td></tr>
</table>

I have following code

$( "#list3 li" ).draggable({
            connectToSortable: "#list2",
            helper: "clone",
            revert: "invalid"
});
$( "#list1 li" ).draggable({
        connectToSortable: "#list2",
        helper: "clone",
        revert: "invalid",
        greedy: true
});

How can i drop list1 item into list2 directly and list2's ul Layout tag which will come from list3 by drag and drop API of jquery?

So what you want to achieve can be summarized like this

Step 1 : Drag and drop some Layout(which is inside li tag) from #list3 to #list2.

Step 2 : Drag and drop some media(which is also inside li tag) from #list1 to #list2 directly and also #list2 Layout's ul tag .drop-container which is now has been dragged to #list2 .

Currently , you are dropping #list1 li into #list 2 , but it should be dropped into .drop-container of #list2 or #list2(if you want to add #list li to #list2 directly)

so #list1 li should be connected to .drop-container of #list2 and #list2

$("#list1 li").draggable({
    connectToSortable: "#list2 .drop-container,#list2",//both element should be connected
    helper: "clone",
    revert: "invalid",
    greedy: true
});

After that, the sortable API needs to be added to .drop-container of #list2 only after #list2 has received some Layout from #list3 of

So call sortable on #list2 .drop-container inside receive method of sortable of list2. Now your receive function of #list2 becomes

receive: function (event, ui) {
        console.log(ui);
        console.log(event);
        var this_id = $(ui.item).attr("id");
        var preview = $(itemContext).html().replace(/<!--/g, '').replace(/-->/g, '');

        $(itemContext).attr("id", this_id);
        $(itemContext).css("width", $('#list2').width() - 20).addClass("ui-state-default").height('auto');
        $(itemContext).html(preview);

 //Modified code starts here, the sortable should be added here

        $("#list2 .drop-container").sortable({//call sortable to every element which you want to drop to.
            connectWith: "#list1",
            over: function () {
                removeIntent = false;
            },
            out: function () {
                removeIntent = true;
            },
            beforeStop: function (event, ui) {
                itemContext = ui.item.context;
                if (removeIntent == true) {
                    ui.item.remove();
                    disp($("#list2").sortable('toArray'));
                }
                //console.log(itemContext);

            },
            receive: function (event, ui) {
                console.log(ui);
                console.log(event);
                var this_id = $(ui.item).attr("id");
                var preview = $(itemContext).html().replace(/<!--/g, '').replace(/-->/g, '');

                $(itemContext).attr("id", this_id);
                $(itemContext).css("width", $('#list2').width() - 20).addClass("ui-state-default").height('auto');
                $(itemContext).html(preview);

                //console.log(this_id);
                //console.log(preview);

            }
        }); //.disableSelection()

    //end of modified code

        //console.log(this_id);
        //console.log(preview);

    }
});
