Angular2 formControl for select multiple
<p>I'm using Sematinc-UI and Angular2 <code>ReactiveFormsModule</code> form and i'd like to use <code>[formControl]</code> for select multiple.</p>

<p>If i use <code>select</code> it works with no problems:</p>

<pre><code>        &lt;select class="ui fluid dropdown" [formControl]="myForm.controls.category"&gt;
            &lt;option *ngFor="let item of categories" value="{{item}}"&gt;{{item}}&lt;/option&gt;
        &lt;/select&gt;
</code></pre>

<p>If i use select multiple it doesn't work:</p>

<pre><code>        &lt;select multiple="" class="ui fluid dropdown" [formControl]="myForm.controls.category"&gt;
            &lt;option *ngFor="let item of categories" value="{{item}}"&gt;{{item}}&lt;/option&gt;
        &lt;/select&gt;
</code></pre>

<p>I get this error:</p>

<p><strong>core.umd.js:3462 EXCEPTION: Uncaught (in promise): Error: Error in <a href="http://localhost:3000/app/components/category.component.js" rel="noreferrer">http://localhost:3000/app/components/category.component.js</a> class CategoryComponent - inline template:0:1701 caused by: values.map is not a function</strong></p>

<p>What could be the problem?</p>
