title: Use dragula to move objects over canvas
body: <p>I have a canvas with a background picture. I would like to have objects (buttons or divs) that can move over the canvas.</p>
  <p>I have found the perfect solution with <a href="http://interactjs.io/" rel="nofollow noreferrer">interact.js</a>. The first example on the page (called Dragging) is exactly what I'd like to achieve. Get the position over the canvas and if the object is moved outside, it goes back inside automatically.</p>
  <p>However, I'm already using <a href="https://github.com/bevacqua/dragula" rel="nofollow noreferrer">dragula</a> to sort items and would like to keep only one library for drag and drop functions. Adding another library would add more complexity to my webapp.</p>
  <p>Is it &quot;easy&quot; to achieve that with dragula? If yes, how?</p>
  <p>A code example is needed in order to understand how.</p>
