How to disable drag some element on ng2-dragula
<p>I want to display name group on the top and cancel the  drag event on it.
How can I disable moving some element like if this group name on the top.
My code is:</p>

<pre><code>dragulaService.drag.subscribe((value) =&gt; {
    console.log(`drag: ${value[0]}`);
});
</code></pre>

<p>My template :</p>

<pre><code>&lt;div class='wrapper'&gt;
  &lt;div class='container' *ngFor='let group of groups' [dragula]='"nested-bag"'&gt;
     &lt;div class="center-block"&gt;Table Number : {{group.name}}&lt;/div&gt;
    &lt;div *ngFor='let item of group.items' [innerHtml]='item.name'&gt;&lt;/div&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code></pre>
