Auto-complete fields on form generation yii2?

Question

Yii

there is such an ActiveForm field

<?= $form
            ->field($model, 'part_number')
            ->textInput([
                'maxlength' => true,
                'id' => 'input2',
                'class' => 'form-control',
                'placeholder' => html::encode($model->getAttributeLabel('part_number')),
                'required' => 'required'
            ])
            ->label(false) ?>

how to make this field filled with certain text initially?
