Behavior

Agree fields use the same checkbox-radio browser behavior as checkbox groups, but as a single consent option:

• required handling still applies at the field level
• checked attributes stay synchronized with live state
• shared checkbox/radio lifecycle events still come through checkbox-radio

Events

Agree fields use the same shared checkbox-radio field events described on JavaScript events.

The formie:field:checkbox-radio:init event

Triggered after the agree field has been wired and its consent checkbox is ready.

document.addEventListener('formie:field:checkbox-radio:init', (event) => {
  const { checkboxRadio } = event.detail;

  // Only target the terms agreement field.
  if (checkboxRadio?.dataset.formieFieldHandle !== 'termsAgreement') {
    return;
  }

  // Mark the field once the consent checkbox is ready.
  checkboxRadio.setAttribute('data-agree-ready', 'true');
});
