You need construct the id as a string not as a array, and it´s the fourth parameter, not the third (the third parameter is the default value)

See the example in docs:

$options = array(
              'small'  => 'Small Shirt',
              'med'    => 'Medium Shirt',
              'large'   => 'Large Shirt',
              'xlarge' => 'Extra Large Shirt',
            );

$js = 'id="shirts" onChange="some_function();"';

echo form_dropdown('shirts', $options, 'large', $js);

"Lets you create a standard drop-down field. The first parameter will contain the name of the field, the second parameter will contain an associative array of options, and the third parameter will contain the value you wish to be selected. You can also pass an array of multiple items through the third parameter, and CodeIgniter will create a multiple select for you."
