Is there any way of being able to determine that an option on a contact form will be unavailable once it exceeds a limit?
For example...
If I was running an event with 3 seminars..
12pm
2pm
4pm
Can I limit them so that when say 20 people choose the 12pm option, 12pm it will be unavailable for the next person filling out the form?
If I can't do this via Contact Form 7 is there another form someone could suggest?
Thanks
