I’ve had my store up for a while now and am looking for a way to have my products shown but allow customers to add some options, preferably with a thumbnail showing the option but not a priority on the thumbnail.
Does anyone know of an extension or add-on that will give me that option?
For example, I sell afghans in various sizes and would an option to select the size. I also make pillows to match the afghan so I would like that option to be available and show and add the price of that option to the order.
I hope there is such a thing.

Assuming pillows are a seperate product, maybe a "product accessory" extension would work for you.

google "opencart product accessories"

Thank you.
Do you know if I can add the options for the main products?

product options are build in and you can add a thumbnail to a option as well
