If the class property is an array, is it possible to access its element from ActiveForm?

Question

Yii

There is this property:

'circles'              => [
            0 => [
                'title' => 'years in IT',
                'titleValue' => 10,
                'data-percents' => 50,
            ],
            1 => [
                'title' => 'developers',
                'titleValue' => 50,
                'data-percents' => 50,
            ],
            2 => [
                'title' => 'projects',
                'titleValue' =>  150,
                'data-percents' => 50,
            ],
            3 => [
                'title' => 'customers & partners',
                'titleValue' => 200,
                'data-percents' => 50,
            ],
        ]

I need to fill it out from a form.
But I don't see any other options than to make a class property for each field that is changed.
It would be cool to write something like:

<?= $form->field($model, "circles['titleValue']") ?>

But this, as expected, does not work. Tell me how to be?
