Usage

Then add Ng2MultiModalComponent and Ng2MultiModalService to your standalone app's component imports:

    imports: [Ng2MultiModalComponent],
    providers: [Ng2MultiModalService]

Required for animations:

export const appConfig: ApplicationConfig = {
  providers: [provideAnimations()]
};

Using the service to create modals dynamically:

import { Ng2MultiModalService } from "ng2-multi-modal";

@Component({
    selector: "app-root",
    templateUrl: "./app.component.html",
    styleUrls: ["./app.component.scss"],
    standalone: true,
    imports: [Ng2MultiModalComponent],
    providers: [Ng2MultiModalService]
})
export class AppComponent {
  readonly theme = model<'light' | 'dark'>('dark');
  tpl = viewChild.required('tpl', {
    read: TemplateRef,
  });

  modals: {
    [key: string]: {
      modal: Ng2MultiModalComponent | null,
      visible: boolean,
    };
  } = {};

  constructor(private _modal: Ng2MultiModalService) {
    effect(() => {
      this._modal.dockTheme.set(this.theme());
    });
  }

  toggleTheme() {
    this.theme.update(prev => (prev === 'light' ? 'dark' : 'light'));
  }

  openModal() {
    this._modal.create({
      content: this.tpl(),
      theme: this.theme
    }).then((modal: Ng2MultiModalComponent) => {
      const key = modal.modalId();
      this.modals[key] = {
        modal,
        visible: true,
      };
      modal.maximized.set(false);
      modal.onClose.subscribe(() => {
        this.modals[key].visible = false;
        this.modals[key].modal = null
      });
    });
  }
}
