yup, i agree..

why dont you try in your controller index?

Code:

...

function index(){
  $options = array(
                  'small'  => 'Small Shirt',
                  'med'    => 'Medium Shirt',
                  'large'   => 'Large Shirt',
                  'xlarge' => 'Extra Large Shirt',
                );
  echo form_dropdown('shirts', $options, 'large');
}
#tat's all .. and press F5 on your browser
