Angular2: Once user is authenticated, navigate to specific routes

I've developed an admin panel with a router for page navigation. The layout of the admin panel includes a sidebar (Component), header (Component), and content (Component). Within the content, I have inserted

<router-outlet></router-outlet>

to display different components based on routing. However, when using the LoginComponent for authorization, both the sidebar and header are displayed due to the

<router-outlet></router-outlet>

being within the content component. To control the visibility of the sidebar and header, I initially used the *ngIf directive, but I believe there may be a better approach. Is there another way to achieve this setup? For reference, my folder structure can be viewed here: https://i.stack.imgur.com/rNMsn.png

To solve this issue, I utilize the "loadChildren" function. The following code is located in app.routing.module.ts:

const routes: Routes = [
       { path: '', redirectTo: '/dashboard', pathMatch: 'full' },
       { path: 'dashboard', loadChildren: () => DashboardModule, canActivate: [AuthGuard]}, 
       { path: 'login',  component: LoginComponent}
 ]

The code snippet below can be found in dashboard-routing.module.ts:

const dashboardRoutes: Routes = [
{
 path: '',
 component: DashboardComponent,
 children : [
       { 
         path: '', 
         children:[
                   { path: 'user',  component: UserComponent, canActivate: [DashboardGuard] },
                   { path: 'user-crud',  component: UserCrudComponent, canActivate: [DashboardGuard] },
                   { path: 'user-crud/:id',  component: UserCrudComponent, canActivate: [DashboardGuard] }
                  ]
       },

In app.component.ts, after authorization, the dashboard.module is loaded and displayed in the <router-outlet></router-outlet> within this component.

import { Component, OnInit} from '@angular/core';
  @Component({
       selector: 'app-root',
       template: '<router-outlet></router-outlet>'
  })

 export class AppComponent implements OnInit {
     constructor(){}
     ngOnInit() {}
 }

Lastly, the content.component.ts file is responsible for displaying all pages within this component.

import { Component, OnInit } from '@angular/core';
   @Component({
       selector: 'app-content',
       template: '<router-outlet></router-outlet>'
   })
export class ContentComponent implements OnInit {
   constructor() {}
   ngOnInit() {}
}
