bootstrap grid with blank form-group col-md-6
<p>I'd like to achieve a grid like down below. There's a problem because I've got form-group as well. And the problem is, col-md-6 before last and the last one doesn't align correctly.</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;form action=""&gt;
  &lt;div class="col-md-1 pull-right text-right padding-right-0"&gt;
    &lt;div class="action-buttons"&gt;
      &lt;a href="#" class="pull-right button-edit-content" data-target="#s3"&gt;
        &lt;i class="fa fa-pencil" aria-hidden="true"&gt;&lt;/i&gt;
      &lt;/a&gt;              
    &lt;/div&gt;
  &lt;/div&gt;
  &lt;div class="form-group col-md-6"&gt;
    &lt;label for=""&gt;label_1&lt;/label&gt;
    &lt;input type="text"&gt;
  &lt;/div&gt;
  &lt;div class="form-group col-md-5"&gt;
    &lt;label for=""&gt;label_2&lt;/label&gt;
    &lt;input type="text"&gt;
  &lt;/div&gt;
  &lt;div class="form-group col-md-6"&gt;
    &lt;label for=""&gt;label_3&lt;/label&gt;
    &lt;input type="text"&gt;
  &lt;/div&gt;
  &lt;div class="form-group col-md-5"&gt;
    &amp;nbsp;
  &lt;/div&gt;
  &lt;div class="form-group col-md-6"&gt;
    &lt;label for=""&gt;label_5&lt;/label&gt;
    &lt;input type="text"&gt;
  &lt;/div&gt;
  &lt;div class="form-group col-md-5"&gt;
    &lt;label for=""&gt;label_6&lt;/label&gt;
    &lt;input type="text"&gt;
  &lt;/div&gt;
&lt;/form&gt;</code></pre>
</div>
</div>
