Angular CDK connecting multiple drop zones with cdkDropListConnectedTo

You can now use a global container with cdkDropListGroup attribute, in which all child containers with cdkDropList attribute are linked together, no need to add all the [cdkDropListConnectedTo] stuff

<div cdkDropListGroup>
    <div cdkDropList>
        <div cdkDrag>Drag Me</div>
    </div>
    <div cdkDropList>
        <div cdkDrag>Drag Me Also</div>
    </div>
    ...
</div>

You can connect to multiple containers, like:

[cdkDropListConnectedTo]="[doneList,doneList1]"

Turns out DragDropscdkDropListConnectedTo connecting to different dropzones e.g

[cdkDropListConnectedTo]="[inProgress, done]"
