When I create a custom field with a regex for validation, the fact that the regex exists seems to force the Custom Field to be a Required field. Is there a way for the Custom Field to be Optional but still have a validation pattern?
You just have to use a regex that allows empty string. If you give us your regexp, I can help you 
Yeah, I suspected something like that, but I’m not sure I know the best way.
Our pattern looks like 20987-333 so the regex I was using is ^\d{5}\-{1}-\d{3}$
Thanks for your reply!
Your current regex won’t match that, it seems it will match 20987--333 though? You can add an optional empty value:
^\d{5}-{1}-\d{3}$|$^
This interface was munging my regex. I’ll try to do a code block.
I think this is what I was using.
^\d{5}\-{1}\d{3}$
^\d{5}\-{1}\d{3}$|^$
This seems to work great for me. thanks for your help!
