I use Codeigniter PHP. How can i use the search option with datatable search (datatable MD5)? In the documentation and sample video they use javascipt. I know it fully works with the original datatable repository, but i want it to work with the MD 5 version. Below an example with a foreach loop.

<div class="card-body">
            <h4 class="header-title"><a class="btn btn-primary btn-rounded width-md waves-effect waves-light mb-4" href="<?= route_to('department_new') ?>">Nieuw</a></h4>

            <?php if (isset($departments) && count($departments)) : ?>
                <table id="department-datatable" class="table dt-responsive nowrap w-100">
                    <thead>
                    <tr>
                        <th>Id</th>
                        <th>Naam</th>
                        <th>Omschrijving</th>
                        <th>Gemaakt op</th>
                        <th>Acties</th>
                    </tr>
                    </thead>
                    <tbody>
                    <?php foreach ($departments as $item): ?>
                        <tr>
                            <td><?= $item->id ?></td>
                            <td><?= $item->name ?></td>
                            <td><?= $item->description ?></td>
                            <td><?= $item->created_at ?></td>
                            <td>
                                <a class="btn btn-purple waves-effect waves-light" href="<?= route_to('department_show', $item->id) ?>">Bekijken</a>
                                <a class="btn btn-info waves-effect waves-light" href="<?= route_to('department_index') ?>">Locaties</a>
                            </td>
                        </tr>
                    <?php endforeach; ?>
                    </tbody>
                </table>

            <?php else : ?>

                <h4 class="text-center">Helaas er zijn geen afdelingen gevonden</h4>

            <?php endif ?>

        </div> <!-- end card body-->
