Tabular input with related data?

Question

Yii

there are 2 tables:
option - id, name
page_option - id, option_id, lang_id,
value

public function getPageOption()
    {
        return $this->hasOne(PageOption::className(), ['option_id' => 'id']);
    }

Everything finds, everything works, but I can’t figure out how to work with the form if we have a tabular input?
here is the form:

.. active form begin
foreach ($options as $index => $option) {
    echo $form->field($option, "[$index]pageOption[value]")->label($option->name);
}
.. active form end

It outputs, but only the id and name of all these fields are the same: pageOption[value]
and how to work with this is not clear
UPD, we figured it out, now the problem is saving the associated data:
controller/action:

public function actionUpdate()
    {
        $options = Options::find()->with('pageOptions')->indexBy('id');
        
        if (Model::loadMultiple($options , \Yii::$app->request->post()) && Model::validateMultiple($options)) {
           
            foreach ($options  as $option) {
                $setting->save(false);
            }
        }
        
        return $this->render('index', compact("options"));
    }

Eventually:

Model::loadMultiple($options , \Yii::$app->request->post()) - true

but the related data has not been updated, it turns out that new data is not loaded into them
Please tell me, I'm clearly doing something wrong

if (Model::loadMultiple($options->pageOption , \Yii::$app->request->post()) && Model::validateMultiple($options->pageOption)) {
    foreach ($options->pageOption  as $page) {
                $page->save(false);
    }
}
