Variants and sub variants

Hi,

In my webshop (beds) most products have variants (size) and subvariants (color, etc.).
Only the first variant (size) needs to change the price and customers can select sub variants which do not change the price.

In versions of Hikashop before 2.5.0 I added the variant which changes the price (choosing a size) and I gave these variants a price. After that I added the other variants (such as color, matras, etc) and all variants had the right pricing.

Example: 3 sizes and 10 colors: I added the size variant and had to set a price to the 3 variants. After that I added the color variant, so in total there are 30 variants. All variants have the right pricing.

Now, in version 2.5.0 it seems not possible to first add the variant which changes the price of the product and then add the variants which do not change the price.

Now I need to add a price to ALL 30 variants (in the example mentioned before) which is a lot more work...

Maybe I'm missing something? I did add &legecy=1 to the product-url and tried to add the variants but the only thing what appears is a empty pop-pup.

Kind regards,
Eric
