CheckboxInput typedef
CheckboxInput = $Empty
Checkbox input allows the business to provide a boolean value.
Corresponds to the [html input
type=checkbox](https://www.w3.org/TR/2012/WD-html-markup-20121025/input.checkbox.html#input.checkbox).
If the business checks the box, the input value for the field is true,
otherwise it is false. This type of input is often used as a confirmation
that the business completed required steps before they are allowed to start
the action. In such a case, the input field is marked as required and the
button to trigger the action should stay disabled until the business checks
the box.
Implementation
typedef CheckboxInput = $Empty;
