Full width header & horizontal menu

I'm trying to understand how to do this. Nothing in the documentation says how to make the header area & menu (which I have after making a new template by selecting a preset) full width (that is, page width, not sheet width).

EDIT: Ahhh, OK, I did find how to do this, but that creates another issue. I had to make a new wrapper and make it full width. However, now I have the logo and menu justified way over to the left. I want them to be left justified to the SHEET edge, but the menu and header backgrounds full width.

Hi
look at the help page in the component, there is a video about multibackgrounds
you can use the expert mode to set a background to the page and not only the wrapper block. Then let your wrapper ni normal width to put the other blocks in it

Thanks. I have managed to get it displaying how I want.

So, to insert a module in the page I need first have a wrapper, then a row, correct?

you can insert a module in a wrapper without a row if you want

I tried dragging an existing module (the menu) to a new wrapper but it wouldn't drop into it until I'd added a row with a single column. Perhaps I just didn't hover long enough or in the right place.
