JQuery UI : Drag and Drop : Deal with several containers and overflow property

I am completely stuck on a drag and drop problem: I need to be able to drag the yellow squares located in the cells of the row 1 into one of the cells of the row 3.

I made a small JS Bin example here

My constraints are that all the cells must have the property "overflow" because the cells can have plenty of yellow squares.

I tried to apply the property "clone / original" and "AppendTo" to the draggable elements, but I didn't manage to deal with the main container scrollbar which have the property overflow as well.

Any help would be welcome!

For being able to drag the element to another table cell, you need to set the "helper" option to "clone".

$(this).draggable({
    opacity: 0.7,
    helper: 'clone',
    scroll: false
});

Now in the "drop" event of the droppable, ui.draggable is the element that is being dragged. What you need to do it to append it the droppable.

$(this).droppable({
    ...
    drop: function(event, ui) {
        $(this).addClass("cell-dropped");
        // "ui.draggable" is the element being dragged
        // "this" is the droppable element
        $(ui.draggable).appendTo(this);
    }
});

For the scrolling of the container DIV, you have to explicitly set it's css position value to relative:

.container{
    ...
    position: relative;
}
