When a customer makes a booking or an enquiry they will be required to input several fields including their email address, first name and last name, and mobile number which are mandatory.
By default, the birthday field isn't mandatory, but if you want to, you can make it:
Click Settings, then Sites, and select the site.
Click Booking Types.
Click Required Fields and then select the Birthday check box. You need to repeat this on each booking type you want this to apply to.
Click Save.
Alternatively, if you want to remove the birthday field altogether, select the Birthday check box in the Remove Fields section.
