When I use angular 15, everything is fine.
When I upgrade angular to 17.3.5, and the latest bootstrap, the following error occurs. Please help me!

Hi @lelelethu.

You probably forgot to import the NgbDropdown directive.
If you really think this is a bug in ng-bootstrap, then provide a complete minimal reproduction as a stackblitz.

I doubt this is a bug in ng-bootstrap though. So you should be seeking for help elsewhere, like the Angular Discord or Stackoverflow.
