My main menu is published throughout my site. I do not want the menu to show up when I edit or create a new post. Right now, the menu floats on top and I can't switch between tabs at the top because it covers them. See example.

I would rather not write a css override for this, but is there a way to just have the menu unpublished every time I create or edit a new post? I already unassigned the module in my backend..
