drop zone css + cdk + angular 8 code example

Example 1: angular material drag and drop not working

// what i did was just to restart angular compiler.

Example 2: angular material drag and drop only on button

<div class="example-box" cdkDrag>
  I can only be dragged using the handle

  <div class="example-handle" cdkDragHandle>
    <button class="btn move" cdkDragHandle>
      <mat-icon>open_with</mat-icon>
	</button>
  </div>
</div>
