This could help you :


ZPT

<select name="usernames:list" tal:define="emptylist python:[];
                                           usernames 
python:here.getUsernames();
                                           selectedones request/usernames | 
emptylist">
  <option tal:repeat="username usernames"
                 tal:attributes="selected python:username in selectedones"
                 tal:content="python:username">displayname</option>

</select>
