title: Drupal 7: How can I create a key/value field(or field group, if that's even possible)?
body: <p>Let's say I'm creating some app documentation. In creating a content type for functions, I have a text field for name, a box for a general description, and a couple other basic things. Now I need something for storing arguments to the function. Ideally, I'd like to input these as key-value pairs, or just two related fields, which can then be repeated as many times as needed for the given function. But I can't find any way to accomplish this.</p>
  
  <p>The closest I've gotten is an abandonded <a href="http://drupal.org/project/content_multigroup" rel="nofollow">field  multigroup module</a> that says to wait for CCK3, which hasn't even produced an alpha yet as far as I can tell and whose project page makes no obvious mention of this multi-group functionality. I also checked the CCK issue queue and don't think I saw it in there, either.</p>
  
  <p>Is there a <em>current</em> viable way of doing this I'm not seeing? Viable includes "you're thinking of this the wrong way and do X instead." I've considered using a "Long text and summary" field, but that smells hackish and I don't know if I'd be setting myself up for side-effects. I'm new to Drupal.</p>
