This is good nicolas, I didn't notice these...
With the latest version of HikaShop, there is an option to not generate variants automatically when you add a characteristic to a product. You will find it in the advanced options of the configuration.
So to clarify, this option makes it easier for you to manage how many variants you want to add to each product. Is there any further documentation on this? Just want to make sure I understand it fully before I start making changes
Another possibility is that instead of creating a new product, simply duplicate a product with the variant setup that you want with the "copy" button of the products listing. It should be even faster than creating/deleting the variants in your products since the copy of the product will already contain the variants setup like the original product.
This will be very helpful. Thanks again...
