Missing Chrome Side Bar?

Hello,

When using Google Chrome on my MacbookPro and also MacBook Air device too, I cannot view the top Side bar of Chrome when using the browser in full screen mode. I only display the Side bar when I slide the mouse up to the top. You can see the two screenshoots in below for this two situations.

How can I get the top menu to appear permanently on my mac?

Thanks
