title: Ng-Repeat array to rows and columns
body: <p>Thanks for taking the time to read this, I was wondering how I might be able to use ng-repeat to create a grid like box of options.  I would like to take an array repeat nth number of items and then move to the next row or column until all items are listed. e.g.</p>
  
  <p>assuming I had an array like <code>[opt1,opt2,opt3,opt4,opt5,opt6,opt7]</code> I would like to display it like this:</p>
  
  <pre><code>opt1 opt2 opt3
  opt4 opt5 opt6
  opt7
  </code></pre>
