Changes between Initial Version and Version 1 of Ticket #6009, comment 19

initial	v1
1	1	The only problem here is showing a visual indication. Maybe the label should be part of the widget, so you have something to work with? How often do you use a checkbox without a label? Exactly. But wrap it around the checkbox, don't use an extra one. Makes layout much easier and less error prone.

3		Nonetheless, I think it's worth it to at least support the `required` flag along with a `validate()` method, so you can at least wrap ~~`Form` widget around the checkboxes, and have the form's `validate()` method include them in~~ validation. That would at least put them on equal footing with plain HTML form validation, and not make it worse.

That would at least put them on equal footing with plain HTML form validation, and not make it worse.
