We'll check this.

While on this subject. Please can the id property also be added to the radio group (parent) element?

The first problem should be fixed.

For the second one: the id must be unique on the HTML page.

Yes agreed, however I can't see how the proposed screenshot would make the id not to be unique?

The group (parent) will have id classname_sample_id_name where the group items will have the suffix added to the id name classname_sample_id_name_item_count All the id's are unique, no?

ok, so you don't want to add an id, but an id "root" that will be extended automatically, right?

Please explain why this is absolutely necessary (once class works).
