PHP Html::activeHint方法代码示例

 /**
  * Renders the hint tag.
  * @param string|bool $content the hint content.
  * If `null`, the hint will be generated via [[Model::getAttributeHint()]].
  * If `false`, the generated field will not contain the hint part.
  * Note that this will NOT be [[Html::encode()|encoded]].
  * @param array $options the tag options in terms of name-value pairs. These will be rendered as
  * the attributes of the hint tag. The values will be HTML-encoded using [[Html::encode()]].
  *
  * The following options are specially handled:
  *
  * - `tag`: this specifies the tag name. If not set, `div` will be used.
  *   See also [[\yii\helpers\Html::tag()]].
  *
  * @return $this the field object itself.
