Signature

deduplicateFields( nativeFields: FormField[], customFields: FormField[], ): : FormField[]

Summary

Removes native fields whose underlying element is already contained within a custom component wrapper. Adapter-detected fields take precedence because they carry richer context (label, options, etc.).

Source Code

function deduplicateFields(
  nativeFields: FormField[],
  customFields: FormField[],
): FormField[] {
  if (customFields.length === 0) return nativeFields;

  // Collect all custom wrapper elements
  const customWrappers = new Set(customFields.map((f) => f.element));

  const filtered = nativeFields.filter((nf) => {
    // If the native element is a descendant of any custom wrapper, skip it
    for (const wrapper of customWrappers) {
      if (wrapper.contains(nf.element)) return false;
    }
    return true;
  });

  return [...filtered, ...customFields];
}

No outgoing dependencies.
