Support drag drop of selected items in multi-select combo box

[veenatic82]

Describe your motivation

I want to allow the user to reorder the selected items. For example, user has selected some items from the drop-down and combo-box shows them in the order of selection.

Describe the solution you'd like

the user should be able to drag drop the selected items in the box at the desired position (one at a time) to rearrange the order of selected items. this is especially useful when you set the combo-box property autoExpand and selectedItemsOnTop in v24.6

Describe alternatives you've considered

Alternative is to use grid and use its drag drop feature. but the current way it allows for drag drop is not serving my purpose. For example, when multiple items are selected in the grid using its selection feature. and when user starts to drag, it drags all the selected items and its not very intuitive. i would have wanted an option to allow dragging of just one item.

But I think in the combo-box, its much more intuitive if there was such option
