I am working on a Magento project and I need to know if there is a way to make a product's options independent to each other or unrequired. I need to use one of several at a time (I have 6 dropdowns).
I have tried add to cart by query string but all dropdown values were still required. I also tried to make all the options default, then modify the selected options in the observer, but I did not meet with success. See the screenshot below for more details.
Any help will be appreciated
