type are represented as check boxes. This data type is also refered as boolean.

checkbox field cannot be used. You must use a
drop down option list field with three values, e.g. "Not selected", "Checked", "Unchecked".
Default Value: You may choose the initial setting for this field come as "checked" whenever you start creating a new record.
