Yii Booster Navbar (Bootstrap Navbar) Inner Bar

I am a great fan of YiiBooster already. I tried to search docs, examples and forum and amused by the available helps there. But still could not find / figure out a particular issue.

I want to make a inner navbar with YiiBooster just like in the cniska.net website where you click documentation you can see it. Sorry cant post link here. looks like below.

Can anyone provide any quick tip?

Thanks Ahead.
