I want to add a custom field to my product details. The most important one is “weight”.
I am going to be selling my seafood online and I want to be able to add the weight in a custom tab, this could be based off the shipping weight or a field that I enter manually, it really isnt important.
I made a mock up screenshot of what I want it to look like.
