Reply To: How can I customize the attribute like this?

Great, it works, thanks very much, that’s why I extended the service.

BTW, for the sample link I provide, I can see that he is using woocommerce, and has more than 40 attributes for the product, but it is easy to load the products when select the attributes. I know you said that when attributes are more than 40, woocommerce would use ajax to load the products. Can you please recommend a solution for this, is there any plugin that can make it work? I tried to search it myself, but still find no answer. Thanks very much.
