title: Select2 Dropdown autoselect if only 1 option available
body: <p>I have a select2 dropdown box using remote datasource.</p>
  
  <p>What I would like to do is if/when there is only one option returned by the search, auto select it. ie, the user doesn;t have to click on the option to make the selection.</p>
  
  <pre><code>$("#searchInfo_Entity_Key").select2({
  ajax: {
      url: "/Adjustment/GetEntity",
      dataType: 'json',
      delay: 250,
      data: function (params) {
          return {
              term: params.term, // search term      
          };
      },
      processResults: function (data) {
          return {
              results: data
          };
      },
      results: function (data) {
          return { results: data };
      },
  },
  initSelection: function (element, callback) {
      var data = [];
      callback(data);
  },
  minimumInputLength: 2,
  allowClear: true,
  placeholder: "Select an entity"
  </code></pre>
  
  <p>});</p>
