Yii2: ActiveForm how to work with two models?

Question

Yii

Good afternoon.
There is a form in which there are:
1. inputs, the data from which falls into the record in table1.
2. checkboxes, when selected (or not selected), records should be created (or deleted) in table2.
I really can't figure out how to do it.
Thanks in advance.
