It's not so hard to do recursion using templates as well as without them.
1. Write a template tag that takes one menu item as a parameter. I
don't have enough time to write the whole tag this time, but the
example usage should be like this:
{% load recursive_menu %}
{% menu root_category %}
2. It should return the list of its children parsed in an HTML
template or an empty string, if it has no children.
3. The HTML template should include the same template tag for each child.
{% load recursive_menu %}
{% if category.child_set.count %}
<ul>
{% for item in category.child_set.all() %}
<li>{{ item }}
{% menu item %}</li>
{% endfor %}
</ul>
{% endif %}
