    Check out the Plunker demo.

    The demo folder of the repository contains the same demo as Plunkr that uses SystemJS. To run that demo do an npm install in that folder followed by npm start to serve the demo app.


    npm install ng2-drag-drop --save


    Import default styles

    Import style.css into your index.html. It has a set of default styles that will be applied upon drag operations. This is totally optional and you can modify the styles as per your need. See the Adding visual cues Section.

    <link rel="stylesheet" href="node_modules/ng2-drag-drop/style.css">

    Update SystemJS config

    If you use SystemJS as your module loader then you will need to update the config to load the ng2-drag-drop module.

        map: {
            'ng2-drag-drop': 'node_modules/ng2-drag-drop'
        packages: {
            'ng2-drag-drop':  { main: 'index.js',  defaultExtension: 'js' },

    Import Ng2DragDropModule

    You need to import the Ng2DragDropModule in the module of your app where you want to use it.

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { DemoComponent } from "./components/demo-component";
    import { Ng2DragDropModule } from 'ng2-drag-drop';
      imports: [
      declarations: [DemoComponent],
      bootstrap: [DemoComponent]
    export class AppModule {}

    Use the draggable & droppable directives

    Place the draggable directive on an element that you want to be draggable. The following example makes the List item draggable:

      <li draggable>Coffee</li>
      <li draggable>Tea</li>
      <li draggable>Milk</li>

    Similarly use the droppable directive on an element where you want to drop draggable:

    <div droppable>
      <p>Drop items here</p>

    Restrict Drop based on Scopes

    You can use the dragScope & dropScope property on draggable and droppable respectively to restrict user from dropping a draggable element into a droppable. The Scope properties can be string, an Array of string (to indicate multiple scope) or a function. The scopes must match in both to indicate compatible drag-drop zones.

    In the following example, only the draggable with the drink dropScope can be dropped on the first droppable and both drink and meal can be dropped in the second one.

      <li draggable [dragScope]="'drink'">Coffee</li>
      <li draggable [dragScope]="'drink'">Tea</li>
      <li draggable [dragScope]="'meal'">Biryani</li>
      <li draggable [dragScope]="'meal'">Kebab</li>
    <div droppable [dropScope]="'drink'" [dragOverClass]="'drag-target-border'">
      <p>Only Drinks can be dropped in the above container</p>
    <div droppable [dropScope]="['drink', 'meal']" [dragOverClass]="'drag-target-border'">
      <p>Both Meal and Drinks can be dropped in the above container</p>

    Drop Scope as Functions

    The DropScope of the droppable can be a function whose return value will determine if drop is allowed. This can be useful to implement complex logic that is otherwise not possible with string or array of string.

    <div droppable [dropScope]="dropAllowed" [dragOverClass]="'drag-target-border'">
      <p>Only those items are droppable for which the `isDropAllowed()` function returns true</p>

    Here is how the function is defined in the component:

    export class MyComponent {
      val = 500;
      isDropAllowed = (dragData: any) => {
        return dragData > this.val;

    Notice how the function is defined as an Arrow Function. You need to do this so the lexical scope of this is preserved. You also get the dragData in the parameter so you can compare it with whatever you want.

    If DropScope is a function, it can also return an Observable, which needs to later resolve to true or false. This can help in cases when you need to check asynchronously (eg: via http) whether the drop is allowed.

    export class MyComponent {
      val = 500;
      isDropAllowed = (dragData: any) => {
        // Resolves to true or false after 1 second
        return Observable.of(dragData > this.val).delay(1000);

    Transfer Data via Drag Drop

    You can transfer data from the draggable to the droppable via the dragData property on the draggable directive. The data will be received in the (onDrop) event of the droppable:

    import {Component} from '@angular/core';
        selector: 'app',
        template: `
    <h3>Transfer Data via Drag Drop</h3>
    <div class="row">
        <div class="col-sm-3">
            <ul class="list-group">
                <li draggable *ngFor="let item of items" [dragData]="item" class="list-group-item">{{}}</li>
        <div class="col-sm-3">
        <div class="panel panel-default" droppable (onDrop)="onItemDrop($event)">
            <div class="panel-heading">Drop Items here</div>
                <div class="panel-body">
                    <li *ngFor="let item of droppedItems" class="list-group-item">{{}}</li>
    export class AppComponent {
        items = [
                {name: "Apple", type: "fruit"},
                {name: "Carrot", type: "vegetable"},
                {name: "Orange", type: "fruit"}];
        onItemDrop(e: any) {
            // Get the dropped data here
        constructor() { }

    Drag Handle

    Drag Handle can be defined for a draggable item which will restrict drag of the element unless the item is dragged from the specified element. The handle should be a valid selector string. Example:

    <li draggable [dragHandle]="'.drag-handle'">
       Not Draggable by list item but by the handle only.    
       <div class="pull-right"><i class="drag-handle fa fa-bars fa-lg" aria-hidden="true"></i></div> 

    Drag Helper Image

    By default when an element is dragged, a translucent image is generated from the drag target. This image is generated automatically and varies with browser. A custom image can be used if desired. Pass the url of the image to [dragImage] on the draggable directive.

    <li draggable [dragImage] = "'../../images/drag-helper.png'" >
       Not Draggable by list item but by the handle only.    
       <div class="pull-right"><i class="drag-handle fa fa-bars fa-lg" aria-hidden="true"></i></div> 

    Compatibility: This only works on Chrome & Firefox. Not supported on Edge.

    Adding visual cues


    Both the draggable & droppable directives take a bunch of inputs that let you apply class on various events. You can find the list below. Another thing you can do is clone the style.css that comes with this package and customize it as per your requirement.

    Draggable Directive

    1. dragHandleClass
    2. dragClass
    3. dragTransitClass

    Droppable Directive

    1. dragOverClass
    2. dragHintClass

    Here is how a custom class is applied to a draggable element:

    <div draggable [dragHandleClass]="'my-draggable'">
      <p>Drop items here</p>

    # Limitations This library uses Native Html5 drag & drop API to accomplish what it does. Because of this, certain aspects are not customizable and some UI behaviour is browser specific.

    So if you were to see the demo under Edge or Chrome/Firefox you'll see that these browsers show a different behaviour when an Item is being dragged. Simlarly Edge does not let you set a custom dragImage while others do. Another major issues is that we can't control the opacity of the ghost element of item being dragged.

    To overcome these issues we'll need to implement our own drag drop functionality instead of relying on the Native Html API which at this point in time, is beyond the scope of this component. Libraries like Dragula, JQuery Draggable, Interact.js to name a few, can provide you with alternatives.

    Touch Support

    HTML5 Drag drop is not touch supported but you can use the DragDropTouch Polyfill.


    To start the dev flow on your system, follow these steps:

    1. npm install on the root of this repo.
    2. npm install in the demo folder. This is where the demo app resides. Sort of a test & play yard for ng2-drag-drop package.
    3. Next you need to sym-link your package with the demo folder so your changes to the package are reflected in the demo app. Please remember the demo and the package are seperate apps & the demo app does not get published to npm. To link run npm link on the root of the repo followed by npm link ng2-drag-drop in demo folder. You can read more about npm link here.
    4. Finally run npm run dev at the root. This will open up the demo app in browser.
    5. Now you can make changes to the actual component or the demo app and debug. Please note that changing the code of demo app will autoreload the browser but you'll need to manually refresh the page if you change the component code.

    Note: The steps are a bit involved at this time and will be simplified to an npm script in later releases.
