` ```

            <div class="card card-default">
                <div class="card-header">
                    <h3 class="card-title">Zgłoszenia kontrola jakości do zamknięcia</h3>
                    <div class="card-tools">
                        <button type="button" class="btn btn-tool" data-card-widget="collapse">
                         <i class="fas fa-minus"></i>
                        </button>
                         <button type="button" class="btn btn-tool" data-card-widget="remove">
                         <i class="fas fa-times"></i>
                        </button>
                    </div>
             </div>
      <!-- /.card-header -->
            <div class="card-body">
                <div class="row">

                        <?php  foreach($jobs as $row):  ?>
