Well the piece I’m currently working on is around allowing a user to specify the order in which something appears. So there is a `position` attribute on the model and collections are ordered by it.

So in this scenario the user is dragging collection items into their specified order. Once they release the draggable element, I want to iterate over the hidden `position` fields that each of them has and set them to 1, 2, 3, 4 etc. The code is something like:

```
$(".sortable-list-item").each(function(i, listItem) {
  $(listItem).find(".signatory-fields-position").val(i + 1);
});

```

But of course this is just one example of what I might want to use drag and drop for.
