title: Dropdown css not displaying correctly
body: <p>I'm displaying a drop-down using bootstrap. The problem is the the style isn't being applied to the drop-down.</p>
  
  <p>When I view the Source code it shows...</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      &lt;label class="control-label col-md-2" for="State"&gt;State&lt;/label&gt;
      &lt;div class="col-md-10"&gt;
          &lt;select htmlAttributes="{ class = form-control }" id="State" name="State"&gt;&lt;option 
      value="CT"&gt;CT&lt;/option&gt;
  </code></pre>
  
  <p>Why is the class form-control not being added to the select tag?</p>
  
  <pre><code>&lt;div class="form-group"&gt;
      @Html.LabelFor(m =&gt; m.State, htmlAttributes: new { @class = "control-label col-md-2" })
      &lt;div class="col-md-10"&gt;
          @Html.DropDownListFor(m =&gt; m.State, db.StateDiscountRates.Select(c =&gt; new SelectListItem { Value = c.State, Text = c.State }).ToList().OrderBy(c =&gt; c.Text)
                      .GroupBy(test =&gt; test.Text)
                            .Select(group =&gt; group.First()), new { htmlAttributes = new { @class = "form-control" } })
          @Html.ValidationMessageFor(model =&gt; model.Address, "", new { @class = "text-danger" })
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
