Hi
In current version, when you edit a product in WP backend, you can see “Additional” field in Item details section https://www.dropbox.com/s/n5y8b9tj46w4hqn/Screenshot%202017-12-30%2023.13.29.png?dl=0
Just add your own list as:
Your Parameter: Value
Your Parameter: Value
Your Parameter: Value
If you want to add an icon, write as this example:
E-Commerce: EDD
All the icon set is here: http://fontawesome.io/icons/ replace ‘shopping-cart’ to your icons slug.
It’s a little bit not easy to do if the user don’t know CSS/HTML knowledge, so we will improve this feature in the later version.
Thanks
