Add custom options to dropdown via code in Magento

Question

i had to add custom options automatically when a product is added , the code works fine but i need to create a drop down menu with options and i dont know how to add options to the drop down created , my code is

public function Add_CustomOptions_Automatically($observer) {
    $product = $observer->getEvent()->getProduct();
    $save = false; if (!$product->getOptions()) $save = true;

    $optionData = array(
        'previous_group'    => 'text',
        'title'             => 'Size',
        'type'              => 'drop_down',
        'is_require'        => 0,
        'sort_order'        => 0,
        'price'             => 0,
        'price_type'        => 'fixed');    


    if($save):
        $product->setHasOptions(1)->save();
        $option = Mage::getModel('catalog/product_option')
                    ->setProductId($product->getId())
                    ->setStoreId($product->getStoreId())           
                    ->addData($optionData);

        $option->save();
        $product->addOption($option);
    endif;
}

}

I've created 'type' => 'drop_down' but how can I add options? I have no idea how to add the options, and any help would be very much appreciated.

thanks,

You can supply an array of values to the option array, this will then be added to the option. as below :-)

$product = Mage::getModel('catalog/product');
$product->load(200); // product id here

$opt = array(
    'is_delete'         => 0,
    'is_require'        => false,
    'previous_group'    => '',
    'title'             => 'New Example Option',
    'type'              => 'drop_down',
    'price_type'        => 'fixed',
    'price'             => '20.0000',
    'sort_order'        => 0,
    /** array of values for this option **/
    'values'            => array(
        array(
            'is_delete'     => 0,
            'title'         => 'Option One Here',
            'price_type'    => 'fixed',
            'price'         => 999,
            'sku'           => 'test-sku-here',
            'option_type_id'=> -1,
        ),
        array(
            'is_delete'     => 0,
            'title'         => 'Another Option',
            'price_type'    => 'fixed',
            'price'         => 999,
            'sku'           => 'another-sku-here',
            'option_type_id'=> -1,
    )),
);

$option = Mage::getModel('catalog/product_option')
    ->setProduct($product)
    ->addOption($opt)
    ->saveOptions();

public function Add_CustomOptions_Automatically($observer) {
    $product = $observer->getEvent()->getProduct();

    $optionData = array(
        'previous_group'    => 'text',
        'title'             => 'Size',
        'type'              => 'drop_down',
        'is_require'        => 0,
        'sort_order'        => 0,
        'price'             => 0,
        'price_type'        => 'fixed');

    if(!(bool)$product->getOptions()):
        $product->setHasOptions(true)->save();
        $option = Mage::getModel('catalog/product_option')
                    ->setProductId($product->getId())
                    ->setStoreId($product->getStoreId())           
                    ->addData($optionData);

        // Answer starts here
        $value = Mage::getModel('catalog/product_option_value');
        $value->setOption($option)
              ->setTitle('Hello world!');
        $option->addValue($value);
        // Answer ends here

        $option->save();
        $product->addOption($option);
    endif;
}

As you can see you are adding a Mage_Catalog_Model_Product_Option_Value with a title and associating it with the $option you created. It can also have an SKU, price and sort order. Create as many values as you want in this way.
