Adding the page to the menu

Now that we have our page, it's time to add it to the sidebar menu. To do so, we will extend the default menu template.

Create a new template file located in templates/navigation/ and call it sidebar-menu.html.twig, so that it can replace the original sidebar menu template file:

app/sprinkles/pastries/templates/navigation/sidebar-menu.html.twig

{% extends '@admin/navigation/sidebar-menu.html.twig' %}

{% block navigation %}
    {{ parent() }}
    <li>
        <a href="/pastries"><i class="fa fa-cutlery fa-fw"></i> <span>List of Pastries</span></a>
    </li>
{% endblock %}

The key here is the {% extends '@admin/navigation/sidebar-menu.html.twig' %} part. While our new template overrides the version in the admin sprinkle, we tell our file to use the template from the admin sprinkle as a base. We can then use Twig inheritance to add our new link to the navigation block. See the Extending Templates and Menus recipe for more information about this.

You should now see the new link in the menu:
