The app contains 5 different Sidemenu layouts which you can use in your apps.
HTML code
The HTML code for the sidemenus is sitting in app.component.html itself, same as the main sidemenu.
You can differentiate the Sidemenus by the class="sidemenu-1" and similar.
Similarly, the styles for each Sidemenu are sitting in app.component.scss
Currently, for display purpose, the Sidemenus are shown on the right hand side. But for your app usage, you can use it either on left or right side, by defining side="end" or side="start"
