I'm working on Angular application that use an UMD library for user interface. The problem that i'm facing is that i cannot use ngFor directive on an element from the library for exemple:

<lib-select>
<lib-option *ngFor="let user from users">---</lib-option>
</lib-select>

The above code display an empty select, whereas the bellow doesn't.

<select>
<option *ngFor="let user from users">---</option>
<select>

How can i handle it ?

Thank you for help!

Best regards.
