You need to add Id for dropdownList, like below
echo CHtml::dropDownList('dropit', '',
array(
'Reception'=>'Service Reception',
'SA'=>'ServiceAdvisor','Billing'=>'Billing Staff',
'Parts'=>'Parts
Counter','Cashier'=>'Cashier','Cwd'=>'Customer Welfare
Desk'),
array('prompt'=>'- select -', 'id'=>'dropit')); // added I'd here
