It is possible to add drag and drop support if you use javascript. You would need to find the target elements (the element to be dragged and the element being dragged to) by means of classes or ids using javascript queryselector and then bind the respective events to these elements. However, I have no clue how you could then pass the data from javacript back to mendi.
Follow the link below to see how to listen to drag & drop events.

This is not a complete solution but i hope this can help lead you to a better solution.
