How to render template part of jinja2 parent?

Question

Flask

Hello, there is a basic template

{% block topnav %}
     {% for menu in menus %}

         <a href ='{{  url_for("secWiev", slug ={{menu.slug}})'>{{  menu.name}}</a>

     {% endfor %}


   {% endblock%}



 {% block rightnav %}


  {% endblock%}

The menu variable is passed from the server by the controller, and there is a second template that inherits it.

The question is how to make it possible to define a section in the second template?

{% block rightnav %}


  {% endblock%}

Moreover, the contents of the topnav block would be pulled automatically from the parent.

I'll clarify the question a bit... the successor renders a separate controller, how to make the menu variable available from the parent so as not to pass it explicitly in the successor's controller?

{% block rightnav %}
{% endblock%}
