Droppable is built on top of Draggable and allows you to declare draggable and droppable elements via options.
Droppable fires two events on top of the draggable events: droppable:dropped and droppable:returned.
Droppable elements must begin in an occupied dropzone (see below, Classes and example),
so they may returned if the drag is canceled or returned.

This sample HTML and JavaScript will make .item elements draggable and droppable among all .dropzone elements:
<div class="container">
<div class="dropzone draggable-dropzone--occupied"><div class="item">A</div></div>
<div class="dropzone draggable-dropzone--occupied"><div class="item">B</div></div>
<div class="dropzone draggable-dropzone--occupied"><div class="item">C</div></div>
</div>
<div class="container">
<div class="dropzone"></div>
</div>
<style>
.item { height: 100%; }
.dropzone { outline: solid 1px; height: 50px; }
.draggable-dropzone--occupied { background: lightgreen; }
</style>import { Droppable } from '@shopify/draggable';
const droppable = new Droppable(document.querySelectorAll('.container'), {
draggable: '.item',
dropzone: '.dropzone'
});
droppable.on('droppable:dropped', () => console.log('droppable:dropped'));
droppable.on('droppable:returned', () => console.log('droppable:returned'));
