Hi thanks for the answer, but this will not work for what I am trying to do. I attached a screenshot of the custom fields for you to see.
On the backend I already have the field set to required. Yes, it makes the field required, but If I do not add the option N/A on the backend it autoselects the default value. In my case if I do not have N/A as the default option with a blank value it will autoselect one of my my filter values as a default value which cannot happen. The default value needs to be blank until my client selects an option, that way when you click save in the backend it says field required and will not let you save the product until you fill this out.
If you do what you are saying it saves the product with whatever the default value is which cannot happen.
I understand if you remove the N/A with the blank default value that it will auto select "All" in the front end, but this will just not work with what I am trying to do. Also, I cannot just name the value to "all" either this will not work because all needs to actually be all products and if you do that the word all would show up twice in the dropdown.
How can I get this to happen?
Thanks,
Josh
