A Bootstrap 3 enhanced version of yii\widgets\ActiveForm.

This class mainly adds the $layout property to choose a Bootstrap 3 form layout. So for example to render a horizontal form you would:

use yii\bootstrap\ActiveForm;

$form = ActiveForm::begin(['layout' => 'horizontal'])

This will set default values for the yii\bootstrap\ActiveField to render horizontal form fields. In particular the template is set to {label} {beginWrapper} {input} {error} {endWrapper} {hint} and the horizontalCssClasses are set to:

[
    'offset' => 'col-sm-offset-3',
    'label' => 'col-sm-3',
    'wrapper' => 'col-sm-6',
    'error' => '',
    'hint' => 'col-sm-3',
]

To get a different column layout in horizontal mode you can modify those options through $fieldConfig:

$form = ActiveForm::begin([
    'layout' => 'horizontal',
    'fieldConfig' => [
        'template' => "{label}\n{beginWrapper}\n{input}\n{hint}\n{error}\n{endWrapper}",
        'horizontalCssClasses' => [
            'label' => 'col-sm-4',
            'offset' => 'col-sm-offset-4',
            'wrapper' => 'col-sm-8',
            'error' => '',
            'hint' => '',
        ],
    ],
]);
