title: JS Disable drag and drop (draggable attribute)
body: <p>Using <a href="http://www.w3schools.com/html/html5_draganddrop.asp" rel="nofollow">this</a> method, I have some elements on my page that can be dragged from one column to another. </p>
  
  <p>I would like to be able to make the drag permanent. That is, once an element is dragged (or dropped I guess) ONCE, it can no longer be dragged. </p>
  
  <p>I tried setting draggable to false using <code>setAttribute</code>, but that didn't seem to work.</p>
  
  <p>So how could you (using plain old JS, no jQuery stuff) disable the draggable ability of an element?</p>
  
  <p>I actually searched this and only found stuff about disabling dragging and dropping of files and other stuff onto a page, that is not what I am asking about. Thanks in advance. </p>
