I have been searching the docs but cannot find a simple way of pre-setting an option of the select element to 'selected'.

我剛剛想出了如何去做.
I've just worked out how to do it.
必須使用元素的 setValue() 方法:
You have to use the setValue() method of the element:
$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.
