Yii2 sidebar navigation


Do anyone have working example of yii2 sidebar navigation made with yii\bootstrap\Nav or anything else that is needed ?

I am trying whole day to make one work, but with no success. I have found several examples of bootstrap sidebar menus on internet, but can not make them work in yii2, since Nav widget is generating bunch of tags/classes that I do not need, and do not provide enough options to customize them.

I want to have both normal navigation and plus sidebar one for admin. The reason I am not using clean bootstrap html is activateParents option of Nav widget.

If you have working code, please share. Thanks.
