A checkbox is used to toggle the selection of an option. It can otherwise be viewed as a Boolean or On/Off control. An ordinary HTML checkbox always submits a value of 'on' when checked. If a checkbox is unchecked when the form is submitted, the checkbox control is termed as unsuccessful and does not submit any value at all.
CodeCharge Studio expands on the functionality of the default HTML checkbox by
enabling the user to specify arbitrary values to be associated with the checked
and unchecked states of a checkbox.
