drop down menu - Yii combobox validation -

i developing yii framework

this part of view

echo chtml::dropdownlist('codcity', '',$citylist);

the dropdown filled in end, alternative that

<option value="xx">(select city)</option> <option value="rm">rome</option> <option value="fl">florence</option> ...

from validation viewpoint, first alternative (xx) not valid, while others valid in model have

public function rules() { homecoming array( ... array('codcity', 'compare', 'operator'=>'!=', 'comparevalue'=>'xx' , 'message'=>'please select city'), ... ); }

and validation rule apply codcity field.
