Q:

Mega Menu Width

I have a mega menu that's supposed to have a fixed width within certain boundaries. I am discussing with my designer and developer colleagues cases where the content of the mega menu increases in width. 
Our options are:

Wrap the content in the mega menu in order to keep the mega menu's width preserved.

Allow the mega menu to expand horizontally to a certain limit which is wider than the alignment with the top menu. It's worth noting that the expansion will have to be to the left.

I'd appreciate your thoughts on the issue. 

A:

I would place the top menu below the Logo making use of the full width of the browser window and not wrapping the text. You get more balance in your viewport, don't cover the logo and make room for possible sign in | register links as well as a search field at the very top. Like this:
