Access the data-id of both the element dragged and the element replaced using SortableJS

I can access the id of the element dragged (see the code below) but not sure how to also grab the id of the element replaced.

the JS:

Sortable.create(selection, {
  handle: '.bars-move',
  animation: 150,

  onStart: function (/**Event*/evt) {
    var itemEl = evt.item;
    var data_id = itemEl.getAttribute("data-id");
    },
});

Any ideas please?

On onStart save the current list of ids, and on onEnd refer to this list using evt.newIndex.

var originalList;

var sortable = new Sortable(document.getElementById('items'), {
  onStart: function(evt) {
    originalList = [...document.querySelectorAll("#items > div")].map(el => el.id);
  },

  onEnd: function(evt) {
    console.log("Dragged id: " + evt.item.id + 
            " - Replaced id: " + originalList[evt.newIndex]);
  }
});
.list-group-item { font-size: 10px; padding: 1px 5px!important; width: 150px }
