public static function WebformElementBase::preRenderFixStatesWrapper in Webform 8.5

Same name and namespace in other branches

1. 6.x src/Plugin/WebformElementBase.php \Drupal\webform\Plugin\WebformElementBase::preRenderFixStatesWrapper()

Fix state wrapper.

Notes:

• Certain elements don't support #states so a workaround is to adds a wrapper that renders the #states in a #prefix and #suffix div tag.
• Composite elements tend not to properly handle #states.
• Composite elements need propagate a visible/hidden #states to sub-element required #state.

Parameters

array $element: An element.

Return value

array An element with #states added to the #prefix and #suffix.
