WooCommerce Gravity Forms Product Add Ons Version 3.1.2, Released on 2017-02-16
The WooCommerce Gravity Forms Product Add Ons extension lets you build advanced product configuration forms for any WooCommerce product.
There is another simple product add ons extension for WooCommerce but nothing comes close to the flexibility of Gravity Forms together with the Gravity Forms Product Add Ons Extension you’re viewing right now. You can build extremely complex forms that let your user select combinations of options with validation and dependencies built into the form. If you need a very complex options builder for your products, this is an excellent choice.
