WooCommerce Custom Fields for Variations

I am utilizing the most recent version of WP, AVADA, and WOOCommerce.

I have read Remi’s post titled WooCommerce Custom Fields for Variations.

I need to add eight custom text fields describing various features of a variable product. I would prefer the eight custom fields do not appear until the shopper has dialed down and selected a particular product.

There will be three variations (Color, Size, & Material) so the shopper can dial down to purchase the correct product.

Once all three variations are selected, then the eight custom fields appear so that visitor gets to see all product information prior to purchase.

Remi published his code in 2014, and has since edited and pointed to GitHub for more recent coding. Others contend the latest version of WooCommerce defeats the GitHub code version.

Does anyone know if a current coding solution exists to add custom fields to a variable product and not appear until the shopper selects each of the three variable choices?
