I am upgrading my project from angular2 to angular4.
While upgrading it's showing that ng2-bootstrap is changed to ngx-bootstrap, I have added it in my package.json and updated my modules.
but now when I use
 import { DropdownModule,ModalModule, PaginationModule, DatepickerModule, TabsModule } from 'ngx-bootstrap';
DropdownModule is showing error, its missing
previously it was like
   import { DropdownModule,ModalModule, PaginationModule, DatepickerModule, TabsModule } from 'ngx-bootstrap';
then it was working fine(angular2)
what should i do?
