title: CKEditor edit data-* attributes
body: <p>I need a solution that allows me to add/edit/remove <code>data-*</code> attributes on individual elements in CKEditor without manually adding it directly in the source editors?</p>
  
  <p>I haven't found any config items or plugins that allow me to do this.</p>
  
  <p>How do I go about doing this?</p>
