            path: '/admin',
            name: 'admin',
            component: () => import('../components/pages/admin/DashBoard'),
            redirect: { path: '/admin/category' },
            meta: {
                // layout: 'admin-layout',
                title: 'Админ панель',
                // requiresAuth: true
            },
            children: [
                {

                    name: 'admin.category',
                    component: () => import('../components/pages/admin/Category'),
                    meta: {

                        layout: 'admin-layout',

                    },
                }
