Renders a Bootstrap 6 form with default, horizontal, inline, or floating-label field layouts.

The layout selects the default [`ActiveField`](/docs/extensions/bootstrap6/reference/activefield/index.md) configuration; override it per form through [`$fieldConfig`](/docs/api/yii/widgets/activeform/index.md#property-fieldConfig).
The inline layout adds `row lg:row-cols-auto g-3 align-items-center` to the form, and [`$nativeValidation`](/docs/extensions/bootstrap6/reference/activeform/index.md#property-nativeValidation)
opts the form in to the Bootstrap `:user-invalid` styling with the `data-bs-validate` attribute.
