It too some decision, but mistakes still aren't displayed.
这也是一些决定，但仍然没有显示错误。
$redactor = yii\imperavi\Widget::widget(
[
'model' => $model,
'attribute' => 'text',
'options' => [
'minHeight' => 400,
],
]
);
$form->field($model, 'text', ['template' => "{error}\n{label}\n{hint}\n{$redactor}"])->textarea();
