Zend Framework - Set \'selected\' value in select box dropdown list?

Answer

$user = $form->createElement('select','user')->setLabel('User: ')->setRequired(true);
    foreach($users as $u)
        $user->addMultiOption($u->id,$u->firstname.' '.$u->lastname);

$user->setValue($selected); //$selected is the 'value' of the <option> that you want to apply selected="selected" to.
