All submit buttons contribute their values.

Member previewVariant 4 · 3 implementations · 12 checks per implementation

Case contract

Submit enabled named controls, checked choices and only the actual submitter; emit one ordered pair per selected multiple option without value deduplication.

Why this case matters

A deterministic model of successful form control collection; this isolates one interface invariant without requiring a browser.

One recorded failure
