Anyway to block certain droppable objects

Question

For example if I have object1, object2 and object3 These can only be dropped in Zone1

Then I have object4, object5 and object6 These can only be dropped in Zone2

How could I configure this?

Also I would like object7 to be allowed to drop in either Zone1 or Zone2 but not Zone3

At the moment I have the following configured.

$(document).ready(function () {
        $(".draggable").each(function (index, item)
        {
            $(item).kendoDraggable({
                filter: ".handle",
                hint: function () {
                    return $('#box').clone().css("display", "block");
                },
                dragstart: draggableOnDragStart,
                dragend: draggableOnDragEnd
            });
        });

        $("#droptarget").kendoDropTarget({
            drop: droptargetOnDrop
        });

        $("#droptargetGauges").kendoDropTargetArea({
            filter: ".test1, .test2",
            drop: droptargetOnDrop
        });
    });

but this means that any div with the class draggable can either be dropped in droptarget or droptargetGauges

You can use the group configuration option, which is available for both DropTarget and DropTargetArea:

HTML:

<div id='dragoptions'>
    <div class="draggable dragoption" id="person-one">person one</div>
    <div class="draggable dragoption" id="person-two">person two</div>
    <div class="draggable dragoption2" id="person-three">person three</div>
    <div class="draggable dragoption2" id="person-four">person four</div>
    <div class="draggable dragoption3" id="person-five">person five</div>
</div>
<div id="targets">
    <div class="droptarget type1" id="target1">role a</div>
    <div class="droptarget type1" id="target2">role b</div>
    <div class="droptarget type2" id="target3">role c</div>
</div>

JS:

$("#dragoptions").kendoDraggable({
    filter: ".dragoption",
    group: "roles",
    hint: function (element) {
        return $(element).clone();
    },
    dragstart: draggableOnDragStart,
    dragend: draggableOnDragEnd
});

$("#dragoptions").kendoDraggable({
    filter: ".dragoption2",
    group: "roles2",
    hint: function (element) {
        return $(element).clone();
    },
    dragstart: draggableOnDragStart,
    dragend: draggableOnDragEnd
});

$("#dragoptions").kendoDraggable({
    filter: ".dragoption3",
    group: "both",
    hint: function (element) {
        return $(element).clone();
    },
    dragstart: draggableOnDragStart,
    dragend: draggableOnDragEnd
}); 

$("#target1").kendoDropTarget({
    group: "roles",
    dragenter: droptargetOnDragEnter,
    dragleave: droptargetOnDragLeave,
    drop: onDrop
});

$("#target2").kendoDropTarget({
    group: "roles2",
    dragenter: droptargetOnDragEnter,
    dragleave: droptargetOnDragLeave,
    drop: onDrop
});

$("#targets").kendoDropTargetArea({
    group: "both",
    dragenter: droptargetOnDragEnter,
    dragleave: droptargetOnDragLeave,
    filter: "#target1, #target2",
    drop: onDrop
});

function draggableOnDragStart(e) {
    $(e.currentTarget).addClass("dragging");
}

function draggableOnDragEnd(e) {
    $(".draggable").removeClass("dragging");
}

function droptargetOnDragEnter(e) {
    $(e.dropTarget).addClass("drop");
}

function droptargetOnDragLeave(e) {
    $(".droptarget").removeClass("drop");
}

function onDrop(e) {
    $(".droptarget").removeClass("drop");
}
