  <p>The HTML</p>
  <pre><code>&lt;div class=&quot;form-group &lt;?PHP if(form_error('moa')) echo 'has-error'; ?&gt;&quot;&gt;
  &lt;div class=&quot;row&quot;&gt;
      &lt;label&gt;Maitre d'ouvrage &lt;span class=&quot;text-danger&quot;&gt;*&lt;/span&gt;&lt;/label&gt;
      &lt;a href=&quot;&lt;?=base_url('societe/ajouter?moa')?&gt;&quot; target=&quot;_blank&quot;&gt;&lt;p style=&quot;float:right;&quot;&gt;Ajouter une société&lt;/p&gt;&lt;/a&gt;
  &lt;/div&gt;
  &lt;select class=&quot;select-search-ajax&quot; data-url=&quot;&lt;?=base_url('societe/moa_json')?&gt;&quot; name=&quot;moa&quot;&gt;
  &lt;?PHP
      foreach($societeMoa as $row) {
          if($chantier-&gt;moa==$row-&gt;id_contact) {
              ?&gt;
              &lt;option value=&quot;&lt;?PHP echo $row-&gt;id_contact; ?&gt;&quot; selected=&quot;selected&quot;&gt;&lt;?PHP echo mb_strtoupper($row-&gt;nom_societe).' ('.$row-&gt;nom_contact.' '. $row-&gt;prenom_contact.')'; ?&gt;&lt;/option&gt;
              &lt;?PHP
          }
      }
      ?&gt;
  &lt;/select&gt;
  &lt;?php echo form_error('moa','&lt;span class=&quot;help-block&quot;&gt;','&lt;/span&gt;'); ?&gt;
  &lt;/div&gt;
  </code></pre>
  <p>JS :</p>
  <pre><code>$(document).ready(function(){
  $('.select-search-ajax').each(function(){
      $(this).select2({
          ajax: {
            url: $(this).attr(&quot;data-url&quot;),
            dataType: 'json'
          }, 
          placeholder: 'Selectionnez...',
          allowClear: true,
        });
  });
  });
  </code></pre>
  <p>CSS :</p>
  <pre><code>.select2-selection--single .select2-selection__clear {
  position: relative;
    cursor: pointer;
    float: right;
    font-size: 0;
    line-height: 1;
    margin-top: 2px;
    margin-left: 5px;
    opacity: 0.75;
    filter: alpha(opacity=75);
  }
  </code></pre>
  <p>As I said I dit not edit the css.</p>
