There will be some products that are selectable on my product detail page which you can add cart with a dropdown. I mean there will be 2 products in cart. Maybe the customer doesnt want to add product on dropdown.

How can I add some products on the dropdown in product detail page?

You can always add more items to cart using the related_products field. You can take a look better in checkout/cart/add controller...

You can try it in your product view page something like this:

<input type="hidden" name="related_product" value="a valid product id here" />

This will add your current product and the one specified in the hidden field... U can use your select field normally just having the values as the product ids you want to use.
