I think I'm probably misunderstanding something. The point of a header, footer, and side bars is that they are, more or less, static--saving you from having to edit them on every page. I could be wrong because I have so little experience with block code but, at least in Novator, it looks like you have to set the footer (and maybe other navs) on every single page. Is that by design or is it something the creators are still working on? Same thing with the header categories navigation. Navbar categories usually pop up on a page navigation bar in or under the header when a category is set to active in admin panel, but it looks like it will have to be created manually and, I'm guessing, set on each and every page? Is that right?

Novator Theme

I know this thread is old and the OP has, likely, already resolved, but for anyone else looking for the info and using default Novator template (same file name for the other template but in its folder):

1) In your shop directory, go to \extensions\novator\storefront\view\novator\template\common\header.tpl
2) On line 24, edit <div class="w-auto" style="max-width: 260px"> to the size you desire
3) Save, close, clear cache and refresh

Luck!
