django - display menu and multilevel submenu -

i need display menu list , multilevel submenu list, ex:

menu1 --menu2 ----menu3 --menu4 menu5 --menu6

here code:

model:

class menu(models.model): status = models.booleanfield(default=false) name = models.charfield(max_length=45) parent_id = models.foreignkey(u'self', null=true, blank=true, related_name=u'parent_menu')

view:

menu = {} map(lambda c: menu.setdefault(c.parent_id, []).append(c), \ menu.objects.filter(status=true).select_related('parent_menu')) context['menu'] = menu homecoming context

template:

{% mymenu, mysubmenu in menu.items %} {{ category.name }} {% mysubmenu in mysubmenu %} {{ mysubmenu }} {% endfor %} {% endfor %}

the actual problem is, don´t right list of more 1 level. display like:

menu1 --menu2 menu2 --menu3 --menu4 menu5 --menu6
