Answer 1

you can do this
public function store(Request $request)
{
//SUBMITTING FORM DATA
$form = Form::create([
'user_phone' => $request['user_phone'],
'user_name' => $request['user_name'],
]);
$form_items = [];
foreach($request['formItems'] as $form_item) {
// when the user enter $form_item ['family_name'] && $form_item ['family_phone'] store the FormItem
// or $form_item ['family_name'] || $form_item ['family_phone']
// depending if both are required or not
if($form_item ['family_name'] && $form_item ['family_phone']){
$form_items[] = new FormItem([
'form_id' => $form->id,
'family_name' => $form_item ['family_name'],
'family_phone' => $form_item ['family_phone'],
]);
}
}
$form->formItems()->saveMany($form_items);
}

Answer 2

You could have a checkbox on your form to ask the user if they want to save form items too.
<input type="checkbox" name="save-form-items" value="true" id="save-form-items">
<label for="save-form-items"> Do you want to save form items?</label>
and then in your controller, you can do something like this:
public function store(Request $request)
{
//SUBMITTING FORM DATA
$form = Form::create([
'user_phone' => $request['user_phone'],
'user_name' => $request['user_name'],
]);
if ($request->has('save-form-items')) {
$form_items = [];
foreach($request['formItems'] as $form_item) {
$form_items[] = new FormItem([
'form_id' => $form->id,
'family_name' => $form_item ['family_name'],
'family_phone' => $form_item ['family_phone'],
]);
}
$form->formItems()->saveMany($form_items);
}
}
