Draggable JS, How to fix mirror z-index ?

What is Draggable ? Try this..

Draggable is a modern drag and drop JavaScript library. Lightweight, modular and accessible.

This is how can I implement.

const containers = document.querySelectorAll('.container');
 swappable = new Draggable.Swappable(containers, {
   mirror: {
     constrainDimensions: true,
  },
});

Closely to complete. But when drag object to somewhere z-index looks weird. You can fix by css very fast.

.draggable-mirror { z-index: 99; }

And happy dragging \o/
