    [taskId]="YOUR_TASK_ID" 
    (attachmentClick)="YOUR_HANDLER">
</adf-task-attachment-list>
```

### Properties

If the List is empty, a default "no content" template is displayed.

### How to Add Drag and Drop Functionality

You can wrap the component with an [Upload Drag Area component](upload-drag-area.component.md)
to enable the user to upload attachments for empty lists. When you do this, you can also pass
a custom _no content template_ as shown below. The component invites the user to drag files to
upload whenever the list is empty.

```html
<adf-upload-drag-area
    [parentId]="YOUR_TASK_ID"
    [showNotificationBar]="BOOLEAN">
    <adf-task-attachment-list  
        [taskId]="YOUR_TASK_ID"
        (attachmentClick)="YOUR_HANDLER">
        <adf-empty-list>
            <div adf-empty-list-header>{{This List is empty}}</div>
            <div adf-empty-list-body>{{Drag and drop to upload}}</div>
            <div adf-empty-list-footer>
                <img [src]="Your custom image URL"></div> 
        </adf-empty-list>
    </adf-task-attachment-list>
</adf-upload-drag-area>
```

```ts
import { UploadService } from '@alfresco/adf-core';
import { TaskUploadService } from '@alfresco/adf-process-services';
```

Make sure you override the `UploadService` with the `TaskUploadService`

```ts
@Component({
    selector: 'my-custom-task-attachment',
    providers: [
        { provide: UploadService, useClass: TaskUploadService }
    ]
})
export class MyCustomTaskAttachmentComponent {
    constructor() {}
}
```

[Upload Drag Area Component](./upload-drag-area.component.md)

If the List is empty, the custom no-content template we passed is displayed.
