I created my blog plugin. So I do not need to use default blog menu on main navigation. I just want to remove it. But I cannot.
Event::listen('backend.menu.extendItems', function($manager) {
$manager->removeMainMenuItem('October.Editor', 'editor');
$manager->removeMainMenuItem('October.Media', 'media');
});
This works for removing Editor and Media section for example. But I do not want to remove those. I am trying to remove Blog and Content sections as you can see below.
