Hi
I have not using any shopping cart module, just created a content type (product) and defining several field(attribute) for each product feature.
I want to ask is there any module in Drupal for product comparison or field comparison?
Thanks
No, but there is a way to do it with the Flag module and Views. It will take more work than just turning on a module, but the outcome is the standard product comparison you're looking for. See this article.
