title: AngularJS remove & add select box option if other selection changes
body: <p>I'm looking for a similar solution to a <a href="https://stackoverflow.com/questions/9979025/remove-add-select-box-option-if-other-selection-changes">problem</a> that has been resolved before with the following code:</p>
  
  <p><a href="http://jsfiddle.net/yLCVf/1/" rel="nofollow noreferrer">http://jsfiddle.net/yLCVf/1/</a></p>
  
  <p>This is the JS that I'm needing to use from the above JSFiddle:</p>
  
  <pre><code>$(document).ready(function () {
      $('select.hello').change(function () {
          $('select.hello option').attr('disabled', false);
          $('select.hello').each(function() {
              var val = $(this).find('option:selected').val();
              if (!val) return;
              $('select.hello option').filter(function() {
                  return $(this).val() == val;
              }).attr('disabled', 'disabled');
          });
      });
  });
  </code></pre>
  
  <p>However, I need to do this in AngularJS, and being a newbie to AngularJS I'm a bit stumped how to "convert" some JS into AngularJS Seed and just need a little bit of guidance.</p>
  
  <p>Essentially I have 3 selection drop downs all which contain the same list (It's a list of people), when a user chooses a name for the first selection, I need that name to be removed from the other 2 selection options. The JSfiddle above demonstrates this perfectly, but I just need to understand how I should be placing this code into AngularJS.</p>
  
  <p>Thanks in advance.</p>
