Description

Please extend the configuration with these two parameters:

            appendTo: $(document.body),
            helper: 'clone',

so the dragged element is displayed in front of every element during dragging and can be used with third party extension which creates multi column in elements (e.g. flux)

Here the changed code for typo3/sysext/backend/Resources/Public/JavaScript/LayoutModule/DragDrop.js (starting at line 43)
Insert appendTo and helper in the $(DragDrop.contentIdentifier).draggable configuration:

    DragDrop.initialize = function () {
        $(DragDrop.contentIdentifier).draggable({
            handle: this.dragHeaderIdentifier,
            scope: 'tt_content',
            cursor: 'move',
            distance: 20,
            addClasses: 'active-drag',
            revert: 'invalid',
            zIndex: 100,
            appendTo: $(document.body),
            helper: 'clone',
            start: function (evt, ui) {
                DragDrop.onDragStart($(this));
            },
            stop: function (evt, ui) {
                DragDrop.onDragStop($(this));
            }
        });

Sorry this is the correct changed code:

        $(DragDrop.contentIdentifier).draggable({
            handle: this.dragHeaderIdentifier,
            scope: 'tt_content',
            cursor: 'move',
            distance: 20,
            addClasses: 'active-drag',
            revert: 'invalid',
            zIndex: 100,
            appendTo: $(document.body),
            helper: 'clone',
            create: function(evt, ui) {
            },
            start: function (evt, ui) {
                DragDrop.onDragStart(ui.helper);
            },
            stop: function (evt, ui) {
                DragDrop.onDragStop(ui.helper);
            }
        });

Additional changes: DragDrop.onDragStart(ui.helper); and DragDrop.onDragStop(ui.helper);.
Use ui.helper instead of $(this) otherwise the displayed dragging element is wrong.
