title: Drupal Content Type: how to add a checkbox that hides an object if checked?
body: <p>I am working on a Drupal site and I want to add a checkbox within a content type that will hide an object if checked.</p>
  
  <p>I am not to worried about how to hide it, I can figure that out with Js or CSS later on but I need to know how to add a checkbox that has the ability to modify the display.</p>
  
  <p>I think its going to be along the lines of adding a new field but I don't know what type of field to add.</p>
  
  <p>Any help is greatly appreciated :)</p>
