I have some difficulties with figuring out how to make my modals draggable. I have reusable modals with its own service which is called to create one inside components.
confirm.modal.service.ts
import { Injectable } from "@angular/core";
import { NgbModal } from "@ng-bootstrap/ng-bootstrap";
import { Observable, from, EMPTY, throwError } from "rxjs";
import { catchError, tap } from "rxjs/operators";
import { ConfirmModalComponent } from "./confirm-modal.component";
export interface ConfirmOptions {
title: string;
subtitle?: string;
errorOnClose?: boolean;
}
@Injectable({ providedIn: "root" })
export class ConfirmModalService {
constructor(private modalService: NgbModal) {}
confirm(options: ConfirmOptions): Observable<boolean> {
const modalRef = this.modalService.open(ConfirmModalComponent, {
centered: true
});
modalRef.componentInstance.title = options.title || "Are you sure?";
modalRef.componentInstance.subtitle = options.subtitle || null;
return from(modalRef.result).pipe(
tap(),
catchError(err =>
options.errorOnClose
? throwError(err || "not confirmed")
: EMPTY
)
);
}
}
confirm.modal.module.ts
import { NgModule } from "@angular/core";
import { CommonModule } from "@angular/common";
import { DragDropModule } from "@angular/cdk/drag-drop";
import { ConfirmModalComponent } from "./confirm-modal.component";
@NgModule({
imports: [
CommonModule,
DragDropModule
],
declarations: [ConfirmModalComponent],
exports: [ConfirmModalComponent]
})
export class ConfirmModalModule {}
confirm.modal.component.ts
import { Component, Input } from "@angular/core";
import { NgbActiveModal } from "@ng-bootstrap/ng-bootstrap";
@Component({
selector: "app-confirm-modal",
templateUrl: "./confirm-modal.component.html",
styleUrls: ["./confirm-modal.component.scss"]
})
export class ConfirmModalComponent {
@Input() title: string;
@Input() subtitle: string;
constructor(public activeModal: NgbActiveModal) {}
public accept(): void {
this.activeModal.close(true);
}
public dismiss(): void {
this.activeModal.close(false);
}
}
confirm.modal.component.html
<div class="modal-body">
<div class="modal-body__header">
<span>{{ title }}</span>
</div>
<div *ngIf="subtitle" class="modal-body__text">
<span>{{ subtitle }}</span>
</div>
<div class="modal-body__button-row">
<button class="btn btn-primary" (click)="accept()">Yes</button>
<button class="btn btn-light" (click)="dismiss()">Cancel</button>
</div>
</div>
So I want to make the whole modal be draggable with Angular built-in DragDropModule, hence I should add cdkDrag
inside element with class='modal-content'
but I don't how to achieve that with current setup. NgbModalOptions provides functionality to add class only but not attribute directive.
I know that there is easier solution with JQuery draggable, but I would like to avoid that.
I was thinking about using @ViewChildren for each page but it doesn't seem to the best solution for me.
Thanks for any help!
Just wrap your modal inside a container and add the cdkDragRootElement to it as per the documentation. You will also have to add this class as an option when you open the dialog from the component.ts.
<ng-template #content
let-modal>
<div
cdkDrag
cdkDragRootElement=".your-custom-dialog-class">
<div class="modal-header">
</div>
<div class="modal-body">
</div>
<div class="modal-footer">
</div>
</div>
</ng-template>
The code for the component.ts
const options: NgbModalOptions = {
windowClass: 'your-custom-dialog-class'
};
this.modalService.open(this.content, options);
