How to put the output of ActiveForm:begin()/end() functions into a variable in Yii2?

Question

Yii

I have the following task. I have a widget that should cycle through forms for editing individual rows in the database. Naturally, if I try to add ActiveForm::begin() inside my widget, then the beginning of the form is highlighted at the very beginning of the document before the information in the header. How do I put all my ActiveForms into a variable so that I can display them in the view after that? Or in what other way can I solve my problem without moving the functionality of my widget to the view.

Render the form in a loop:

<?php
    foreach ($items as $num => $item) {
    	echo $this->render('_form', ['model' => $item]);
    } ?>

Or you can render in the field cycle, depending on the situation. There are fields identical that it is possible to apply multiforms.
