Use.php

<?php
    //I use this in method to load menuData by view composer approach. So, I put it in AppServiceProvider
    public function boot()
    {
        view()->composer('layout.main_menu', function ($view) {
            $view->with('adminMenu', MenuBuilder::buildMenuViewObjectFromConfig('launchcms.admin_menu'));
        });
    }
    //When render the menu item, you just need to use main property: label, url on the view. That's it.
