Megameu spreads out and looks weird
The website header is currently appear not centred. Please see screenshot attached for example
I will explain a little bit, because you've added to many categories into your megamenu, now, you menu looks a little awkward, all we need to do now is to make some css adjustment. We can't help that because in the future, if you add or change something, style would be changed as well. So, you need to do it on your own
