I don’t know where did they put the images in slider. I can’t see it in the admin panel. When i go to base.html.twig {% block masterslider %}
{% include ‘partials/masterslider.html.twig’ %}
{% endblock %}

                {% block content %},{% endblock %}
                </div>
            </div>

but i dont know how they use it
