You can try something like

$(".rectagle").draggable({helper: 'clone'});

$("#canvas").droppable({
    accept: ".rectagle",
    drop: function(ev,ui){
        $(ui.draggable).clone().appendTo(this);
    }
});

#canvas {
    height: 100px;
    border: 1px solid lightgrey;
}
.rectagle {
    display: inline-block;
    height: 50px;
    width: 50px;
    border: 1px solid lightblue;
    text-align: center;
    background-color: lightgreen;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="//code.jquery.com/ui/1.11.2/jquery-ui.js"></script>
<div class="rectagle"></div>
<div id="canvas"></div>

function addToolbarItem(graph, toolbar, prototype, image)
     {
        // Function that is executed when the image is dropped on
        // the graph. The cell argument points to the cell under
        // the mousepointer if there is one.
        var funct = function(graph, evt, cell)
        {
            graph.stopEditing(false);
            var pt = graph.getPointForEvent(evt);
            var vertex = graph.getModel().cloneCell(prototype);
            vertex.geometry.x = pt.x;
            vertex.geometry.y = pt.y;

            graph.setSelectionCells(graph.importCells([vertex], 0, 0, cell));
        }
        // Creates the image which is used as the drag icon (preview)
        var img = toolbar.addMode(null, image, funct);
        mxUtils.makeDraggable(img, graph, funct);
    }
