You can configure the `FormModel::class` in two ways. The first way is through the widgets using the `for()`
method `Text::widget()->for(FormModel::class, attribute)`, where the first argument is the `FormModel::class`.
The second way is through the `Field::class` where in each field type the first argument is the
`FormModel::class`, `Field::widget->text(FormModel::class, attribute)`.
