python - Adding CSS item to Django menu -

i need add css classes menu items. can not figure out how that...

i using django cms, not want client alter menu. have far:

from menus.base import menu, navigationnode menus.menu_pool import menu_pool django.utils.translation import ugettext_lazy _  class mymenu(menu):      def get_nodes(self, request):         nodes = []         n1 = navigationnode(_('start'), "/", 1)         n2 = navigationnode(_('item 1'), "item1/", 2)         n3 = navigationnode(_('item 2'), "item2/", 3)         nodes.append(n1)         nodes.append(n2)         nodes.append(n3)         return nodes  menu_pool.register_menu(mymenu) 

my menu looks this:

<ul> <li class="child selected"><a href="/">start</a></li> <li class="child sibling"><a href="item1/">item 1</a></li> <li class="child sibling"><a href="item2/">item 2</a></li>               </ul> 

but want this:

<ul> <li class="start child selected"><a href="/">start</a></li> <li class="item1 child sibling"><a href="item1/">item 1</a></li> <li class="item2 child sibling"><a href="item2/">item 2</a></li>             </ul> 

so think need modifier, can not find proper documentation.

i new django, sure miss lot, step step hope done :) in advance!

the show_menu tag renders navigation of current page. can overwrite appearance , html if add menu/menu.html template project. from docs

so in menu.html like:

{% child in children %}   here can adjust apperance {% endfor %} 

this menu.html used projects: http://pastebin.com/jmzz1gqe
