Django CMS multilingual drop-down menu

I love the new Django CMS, and I try my best to avoid questions, but it drives me crazy. I made a Wiki application with a theme and category model. I connected it to the site on my CMS and added it to my menu. Now I would like to show all the top-level categories, their categories and topics for children, as well as categories of children, etc. In my menu.

Menu/Navigation should look like this:

Wiki
    Category1
        Category1.1
            Topic
        Category1.2
        Topic
    Category2
        Topic
    Category3
        ...

Right now i can only show the Top categories:

Wiki
    Category1
    Category2
    Category3

I already created menu.py to get a custom SubMenu on my wiki (the one you see above):

menu.py

class WikiSubMenu(CMSAttachMenu):
    name = _("Wiki Sub-Menu")

    def get_nodes(self, request):
        nodes = []
        categories = Category.objects.filter(parent_id__isnull=True)

        for c in categories:
            node = NavigationNode(
                mark_safe(c.name),
                c.get_absolute_url(),
                c.id,

            )

            nodes.append(node)

        return nodes

menu_pool.register_menu(WikiSubMenu)

Model of my category:

class Category(models.Model):
    ''' Category model. '''
    name = models.CharField(max_length=100)
    slug = models.SlugField(unique=True)
    description = models.TextField(blank=True)
    parent = models.ForeignKey(
        'self',
        null=True,
        blank=True,
        related_name='children'
    )
    sort = models.IntegerField(default=0)

    class Meta:
        ordering = ['sort', 'name']

    def __unicode__(self):
        return self.name

    @models.permalink
    def get_absolute_url(self):
        return ('topics:categories_category_detail', (), {'slug': self.slug})

    def get_all_children(self):
        return Category.objects.filter(parent=self)

Now, is it possible to create Sub-SubMenu for all categories with children and their children and their children, etc.?

Thanks for the help and sorry for the bad English
