When using the dropdown menu to display the django-mptt tree, nesting is not fully displayed. How to make the tree displayed completely?

Question

Django

When using normal recursion to display the tree, everything is displayed fine


. But I need a drop-down list, and in this case, not full nesting is displayed, but only up to the second level. I don't understand why, please help.


Here is the code from the template:

{% load mptt_tags %}
    {% recursetree rubrics %}
<ul class="nav">

        <li class="nav-item dropright">
            <a class="nav-link dropdown-toggle" data-toggle="dropdown" href="#" role="button" aria-expanded="false"> {{ node.name }}</a>
            {% if not node.is_leaf_node %}
                <ul class="dropdown-menu">
                    <li><a class="dropdown-item">{{ children }}</a></li>
                </ul>
            {% endif %}


</ul>
    {% endrecursetree %}
