Tick box option for custom fields

The custom fields only allow text. This means that you cannot have options on your booking form for tick boxes and indication about whether the guest is required to tick them or not.
For example, you could have information that guests are required to tick to show they have read it; you could have questions such as "I require a baby crib"

Yep, we've got plans to add additional data types for custom fields so you can be a little more flexible.
