Add a custom highlight to the magenta grid

Question

I am trying to add a custom dropdown using (select / options) in my magento grid, but this will not work, I tried using

$this->addColumn('dropdown', array(
'header' => Mage::helper('catalog')->__('Dropdown'),
'filter'    => false,
'sortable'  => false,
'type'=> 'options',
'options' => array('First'=>'firstvalue', 'second' =>'secondvalue')
));

I do not use the value from the database, but from the API, first I want to display this select dropdown menu on my grid, but all I see is empty space.
Thanks.

EDIT:

Actually, I need to make the first line with a drop-down list, and the second line - what I get from the code that I provided.
I can add a link such as a "view" column, but it doesn’t work for the dropdown menu
