Is there a Yii2 widget for editing many-to-many relationships?

Question

Yii

If you want to edit a record that has a Many-to-One relationship, a simple dropDownList will suffice in many cases. Which will display a drop-down list on the form. In the case of a many-to-many connection, the necessary, ready-made widget was not at hand.
Has anyone come across and can advise?
