About

Observable powered drag and drop for angular 10.0+

Installation

Install through npm:

npm install angular-draggable-droppable

Then use it in your app like so:

import { Component, NgModule } from '@angular/core';
import { DragAndDropModule } from 'angular-draggable-droppable';

@NgModule({
  declarations: [DemoApp],
  imports: [DragAndDropModule],
  bootstrap: [DemoApp],
})
class DemoModule {}

@Component({
  selector: 'demo-app',
  template: `
    <div mwlDraggable (dragEnd)="dragEnd($event)">Drag me!</div>
    <div mwlDroppable (drop)="this.droppedData = $event.dropData">
      <span [hidden]="droppedData">Drop here</span>
      <span [hidden]="!droppedData"
        >Item dropped here with data: "{{ droppedData }}"!</span
      >
    </div>
  `,
})
class DemoApp {
  droppedData: string;

  dragEnd(event) {
    console.log('Element was dragged', event);
  }
}

Note: if draggable elements are inside a scrollable element then you will need to add mwlDraggableScrollContainer as an attribute to the scrollable container.

Alternatives

I wrote this library because I needed drag and drop whilst snapping to a grid. If you don't need this feature then I recommend checking out one of these other awesome drag and drop libraries:

• Angular CDK drag and drop
• angular-skyhook
• ng-drag-drop
