You may use properties id and cdkDropListConnectedTo to link both lists:

Component 1:

<div cdkDropList id="list-1" cdkDropListConnectedTo="list-2" (cdkDropListDropped)="drop($event)">

    <div *ngFor="let item of list" cdkDrag>{{ item }}</div>

</div>

Component 2:

<div cdkDropList id="list-2" cdkDropListConnectedTo="list-1" (cdkDropListDropped)="drop($event)">

  <div *ngFor="let item of list" cdkDrag>{{ item }}</div>

</div>

If you need to connect several lists to one list, you may use the following syntax: [cdkDropListConnectedTo]="['list-1', 'list-2', 'list-3', 'list-4']"

After linking the lists, you must correctly update one or both lists depending on the actions. You may do it on the drop function like this:

drop(event: CdkDragDrop<string>) {

    if (event.container.id === event.previousContainer.id) {

      // move inside same list

      moveItemInArray(this.list, event.previousIndex, event.currentIndex);

    } else {

      // move between lists

    }

}

For moving items between lists, you will possibly want to keep track of the lists centrally. You may do so by using a Service, a Store or other methods.

in angular 7.2.1 i had to use around cdkDropListConnectedTo to work even with one list. [cdkDropListConnectedTo]="[list-1]" or [cdkDropListConnectedTo]="['list-1']"

@Dirk tested it with angular 7.2.0 and angular material/cdk 7.2.1 and it worked using the same syntax as before: cdkDropListConnectedTo="list-1"

It did not work for me and thus after some hard time - I managed to make it work using cdkDropListGroup directive. All cdkDropList within cdkDropListGroup will be available to drop items. You no longer need to connect Drop Lists with cdkDropListConnectedTo property

<div cdkDropListGroup>

<component1></component1>

<component2></component2>

</div>
