title: A Choose preference by dragging input field?
body: <p>I have a form and would like to achieve the following effective</p>
  
  <p>Preference for Option A --------------|----------------Preference for Option B</p>
  
  <p>The use is then able to drag to indicate his level of preference. </p>
  
  <p>I'm pretty sure some library exists that already achieves this, but I for the heck of me can't figure out what I would call it, to make a correct search. </p>
  
  <p>Does this exist?</p>
