We use standard itemBoxes segments to set up two two collections of itemBoxes without headers. Each of the inner boxes contains draggable images. Experiment with open , drag images and close.

Or you can ( and try to drag them home)

function randomize(){
  var logos=document.querySelectorAll(".logo");
  for(var i=0;i< logos.length;i++)
  {
    var T=Math.floor(Math.random() * (500 - 100) + 100);
    var L=Math.floor(Math.random() * (500 - 10) + 10);
    
    itemHolder.setPosition(logos[i].parentNode,L,T);
    // or
    //var box=itemHolder.getBoxById(logos[i].getAttribute("id"));
    //box.setCurrentPos(L,T);
  }
}
