I'm trying to use the Angular Material CDK DragDrop module from https://material.angular.io/cdk/drag-drop/overview

With the cdkDropListDropped event I can prevent dropping but it shouldn't be dragged either. How can I tell a cdkDropList or each cdkDrag elements to disable dragging?

<div class="list-group" id="orderlist" cdkDropList (cdkDropListDropped)="drop($event)">
 <a class="list-group-item" 
 [class.linked]="ord.linkedToPrevious" 
 [class.selected]="ord.selected"
 *ngFor="let ord of items" (click)="selectOrder(ord, $event)" cdkDrag>
 <button class="btn btn-default btn-link linkeditem" [class.linked]="ord.linkedToPrevious" 
 (click)="linkTechnology(ord, $event)" 
 [attr.disabled]="editing ? null : true">
 <span class="glyphicon glyphicon-link"></span>
 </button>
 <h4>ord.technology.name</h4>
 </a>
 </div>

You can use cdkDragHandle with Property binding with “class” some property like on or off something like toggle.

<div class="example-handle" [class.your-css-class]="!editing" cdkDragHandle>
<svg width="24px" fill="currentColor" viewBox="0 0 24 24">
 <path d="M10 9h4V6h3l-5-5-5 5h3v3zm-1 1H6V7l-5 5 5 5v-3h3v-4zm14 2l-5-5v3h-3v4h3v3l5-5zm-9 3h-4v3H7l5 5 5-5h-3v-3z"></path>
 <path d="M0 0h24v24H0z" fill="none"></path>
</svg>

.your-css-class
display: none

Disable dragging
If you want to disable dragging for a particular drag item, you can do so by setting the cdkDragDisabled input on a cdkDrag item. Furthermore, you can disable an entire list using the cdkDropListDisabled input on a cdkDropList or a particular handle via cdkDragHandleDisabled on cdkDragHandle.

<div cdkDropList class="example-list" (cdkDropListDropped)="drop($event)">
 <div
 class="example-box"
 *ngFor="let item of items"
 cdkDrag
 [cdkDragDisabled]="item.disabled">item.value</div>
</div>

If you want to disable dragging for a particular drag item, you can do so by setting the cdkDragDisabled input on a cdkDrag item.

<div cdkDropList class="list" (cdkDropListDropped)="drop($event)">
<div *ngFor="let item of dragedItems" cdkDrag 
[cdkDragDisabled]="item.disabled"> item.value </div>
</div>
