Hi, I'm trying to use a drop-down menu in order to insert an optional argument, but I couldn't find a way to do that. I tried ?{Use special?|Yes, --special|No,}
But if I choose 'No', then the option displays No, when I would like an empty string. I tried with a blank, as this would also be ok for my case, but using "|No, }" and choosing No displays No again. If I use quotes, then I see the quotes, so the result is not blank or empty. Do you have any idea how to produce an empty or blank value in a drop-down prompt?
