[web2py] ul, setting the active li

[Annet]

In a view I have the following ul containing the navigation for that view:

<ul class="nav">
  <li><a onclick={{="web2py_component('%s','component')" 
%URL('addressbook','contact.load',args=organization.nodeID)}}>Home</a></li>
  {{if vevent.opening_hours:}}
     <li><a onclick={{="web2py_component('%s','component')" 
%URL('calendar','openingHours.load',args=organization.nodeID)}}>Openingtijden</a></li>
  {{pass}}
  {{if vevent.event_list:}}
    <li><a onclick={{="web2py_component('%s','component')" 
%URL('calendar','eventList.load',args=organization.nodeID)}}>Event 
list</a></li>
  {{pass}}
  {{if vevent.timetable:}}
    <li><a onclick={{="web2py_component('%s','component')" 
%URL('calendar','timetable.load',args=organization.nodeID)}}>Lesrooster</a></li>
  {{pass}}
  {{if vevent.course_table:}}
    <li><a onclick={{="web2py_component('%s','component')" 
%URL('calendar','coursetable.load',args=organization.nodeID)}}>Cursusrooster</a></li>
   {{pass}}
</ul>

Whether an li is there depends on the permissions of the user. At the 
moment the ul is sort of stateless. When the following url is visited: 
http://127.0.0.1:8000/bootstrap/calendar/index/283 no li is active, whereas 
I would like home to be active. When the visitor clicks one of the other  
li that li should become the active one. Is there a way to get this to work.


Kind regards,

Annet
