        &lt;/select&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="col-md-3"&gt;
      &lt;div class="form-group"&gt;
        &lt;label class="control-label" for="date_deb"&gt;Date D&amp;eacute;but&lt;/label&gt;
        &lt;select name="date_deb" id="date_deb" class="form-control"&gt;
          &lt;option value="07/11/2012"&gt;07/11/2012&lt;/option&gt;
          &lt;option value="30/09/2012"&gt;30/09/2012&lt;/option&gt;
        &lt;/select&gt;
      &lt;/div&gt;
    &lt;/div&gt;
    &lt;div class="col-md-3"&gt;
      &lt;div class="form-group"&gt;
        &lt;label class="control-label" for="date_deb"&gt;Date D&amp;eacute;but&lt;/label&gt;
        &lt;select name="date_deb" id="date_deb" class="form-control"&gt;

    &lt;/div&gt;
    &lt;div class="col-md-3"&gt;
      &lt;br/&gt;
      &lt;button type="submit" class="btn btn-success" id="date_search"&gt;Rechercher&lt;/button&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  <p>and this other solution with inline class :</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;script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"&gt;&lt;/script&gt;
