Description Mounir Lamouri 2010-11-04 00:21:36 UTC 
Currently, when a radio button is required, it will suffer from being missing if no radio elements in the radio button group is checked. However, radio elements in the group will not suffer from being missing if they do not have the required attribute. In other words, if you try to style invalid elements with :invalid, and do:
<input type='radio' name='s' value='M' required>
<input type='radio' name='s' value='F'>
only the first element will be styled.

I think we should move the requirement to the radio button group that way: "The radio button group suffers from being missing if one of the input elements in the radio button group is required and all of them have a checkedness that is false." and radio elements would have this constraint: "If the radio button group is suffering from being missing, the element is suffering from being missing.".

That way, all radio elements in the same radio button group will have the same validity state. That would be less annoying for authors and error proof while making things clearer (IMO).

Comment 4 Mounir Lamouri 2011-02-10 09:20:06 UTC 
FWIW, it's implemented in current Firefox betas.
Comment 5 Ian 'Hixie' Hickson 2011-03-04 23:42:34 UTC 
Opera does what the spec says; Firefox does what this proposal says.
Are there any other implementations of required="" on radio buttons?

Comment 6 Mounir Lamouri 2011-03-06 13:09:46 UTC 
Anne, I think you agreed with this change when I sent an email to the mailing list. Do Opera has plan to update its implementation?
Comment 7 Anne 2011-03-06 14:00:40 UTC 
No immediate plans, but we are definitely cool with changing our behavior for the better in due course. That's even easier if the specification requires it to be different and there's testcases effectively "blaming" us for being too fast with implementing this stuff :-)

Checked in as WHATWG revision r6094.
Check-in comment: Make it so that if you make one <input type=radio> required, they all end up required.
