How to attach a HEADER on Layout?

I need to keep a header on the top of the page which contains a logo, a title, and some links.

It seems the Layout can only attach a menu and a toolbar through dhxLayout.attachMenu() and dhxLayout.attachToolbar(). Is there any way to attch a header such as dhxLayout.attachHeader() on top of the layout menu?

I tried to make a top-cell and embed my logo and title into it. I wonder how to attach a menu and toolbar on the bottom of this cell.

Please advise!

Thanks,

You can try to attach div via attachObject with structure as below:
divHeader
dhxMenuDiv
dhxToolbarDiv
