  <pre><code>'@SBCPlatformBundle/Resources/public/jquery/dist/jquery.min.js'         
              '@SBCPlatformBundle/Resources/public/bootstrap/dist/js/bootstrap.min.js'
              '@TetranzSelect2EntityBundle/Resources/public/js/select2entity.js'
  </code></pre>
  
  <p>and my XXXType (Form) :</p>
  
  <pre><code> -&gt;add('fournisseur', Select2EntityType::class, [
          'multiple' =&gt; false,
          'remote_route' =&gt; 'fournisseur_home',
          'class' =&gt; 'SBCPlatformBundle:fournisseur',
          'primary_key' =&gt; 'id',
          'text_property' =&gt; 'name',
          'minimum_input_length' =&gt; 2,
          'page_limit' =&gt; 10,
          'allow_clear' =&gt; true,
          'delay' =&gt; 250,
          'cache' =&gt; true,
          'cache_timeout' =&gt; 60000, // if 'cache' is true
          'language' =&gt; 'fr',
          'placeholder' =&gt; 'Choisir ...',
