I was wondering how can i do mask like this or is it even possible :
I would need to allow user to add field with numbers and letters and hyphen.
But seems that hyphen is not possible when using 9, a, *, ? etc…
So field should be able to enter:
999999-999a or 999999999
But i can’t input hyphen there if * is valid and when there is hyphen i can’t put alphabet there…
for example would like to add to field 100188-133m or 100188A133m but hyphen can’t be added there…
How can i allow also special characters like hyphen for example * or a ? or any other solutions?
Thank you for all the help!
