[web2py] render rows into bootstrap navbar with dropdown menus

[Annet]

The following rows are the result of a query:

id    name              controller    function          parentID

1    home               site             index               0
2    about               about          index               0
3    who_we_are    about         whoWeAre       2
4    what_we_do    about         whatWeDo       2
5    how_we_work  about         howWeWork    2
6    calendar           calendar    index                0
7    opening_hours calendar    openingHours  6
8    event_list         calendar     eventListe        6
9    timetable         calendar      timetable         6
10  course_table   calendar     courseTable     6


In a view, I'd like to render them into a bootstrap navbar with dropdown 
menus: http://twitter.github.com/bootstrap/components.html#navba
This is what the code in the view should look like, what is the python code 
to get the rows rendered like this?

<ul class="nav">
  <li class="active">
    <a href="site/index">Home</a>
  </li>
  <li class="dropdown">
    <a href="about/index" class="dropdown-toggle" 
data-toggle="dropdown">About
    <b class="caret"></b></a>
    <ul class="dropdown-menu">
      <li>
        <a href="about/whoWeAre">who_we_are</a>
      </li>
      <li>
        <a href="about/whatWeDo">what_we_do</a>
      </li>
      <li>
        <a href="about/howWeWork">how_we_work</a>
      </li>
    </ul>
  </li>
 <li class="dropdown">
    <a href="calendar/index" class="dropdown-toggle" 
data-toggle="dropdown">Calendar
    <b class="caret"></b></a>
    <ul class="dropdown-menu">
      <li>
        <a href="calendar/openingHours">opening_hours</a>
      </li>
      <li>
        <a href="calendar/eventList">event_list</a>
      </li>
      <li>
        <a href="calendar/timetable">timetable</a>
      </li>
      <li>
        <a href="calendar/courseTable">course_table</a>
      </li>
    </ul>
  </li>
</ul>


Kind regards,

Annet
