Hi,

I'm building an Angular app, and I'd like to add in a navbar, but it seems I can't.

These are the exact steps to reproduce the error.

ng new navtest
    routing?      Yes
    stylesheet?   SCSS

cd navtest

npm install git+https://oauth2:MY-AUTH-TOKEN@git.mdbootstrap.com/mdb/angular/mdb5/prd/mdb5-angular-ui-kit-pro-essential

ng add mdb-angular-ui-kit
    import all modules?     Yes
    Roboto?                 Yes
    browser animations?     Yes
    Font Awesome?           Yes
    charts?                 Yes

Then for my app.component files, I paste this example:

app.component.html

<header class="h-100">
<mdb-navbar SideClass="navbar fixed-top navbar-expand-lg navbar-dark scrolling-navbar intro-fixed-nav" [containerInside]="false">
