How to fix   Long Method    Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

Commonly applied refactorings include:

It seems like $header can also be of type null; however, parameter $header of Yiisoft\Yii\Bootstrap5\Accordion::renderItem() does only seem to accept string, maybe add an additional type check? ( Ignorable by Annotation )
