title: Angular 8 drop down selected option not showing, how come?
body: <p>This question has been asked frequently. My situation is apparently different from all the others as I can't find a solution for it from the existing answers.</p>
  
  <p>I have this code:</p>
  
  <pre><code>&lt;form (ngSubmit)="getExceptions(f)" #f="ngForm"&gt;
            &lt;div class="row"&gt;
              &lt;div class="form-group col-xs-3 col-sm-3"&gt;
                &lt;label class="col-form-label" for="aantal"&gt;Aantal meldingen per pagina?&lt;/label&gt;
                &lt;select name="selectedQuantity" id="aantal" class="form-control" ngModel&gt;
                  &lt;option *ngFor="let option of options" [value]="option"&gt;{{option}}&lt;/option&gt;
  
                &lt;/select&gt;
              &lt;/div&gt;
  .
  .
  .
  &lt;/form&gt;
  </code></pre>
  
  <p>options is defined as: </p>
  
  <pre><code>private options: string[] = ['10', '20', '50'];
  </code></pre>
  
  <p>I would like to show "10" as the default selected value but whatever I do the drop down keeps showing a blank for the selected value. Clicking the drop down shows the values 10, 20 and 30. So it is filled properly.</p>
  
  <p>What did I try:</p>
  
  <pre><code>&lt;option *ngFor="let option of options" [value]="option" [selected]="option==10"&gt;{{option}}
  &lt;/option&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;option [value]="10" [selected]="true == true"&gt;10&lt;/option&gt;
  &lt;option [value]="20"&gt;20&lt;/option&gt;
  &lt;option [value]="50"&gt;50&lt;/option&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;option [value]="10" selected&gt;10&lt;/option&gt;
  &lt;option [value]="20"&gt;20&lt;/option&gt;
  &lt;option [value]="50"&gt;50&lt;/option&gt;
  </code></pre>
  
  <p>It has something to do with the binding because if I remove the 'ngModel' from the select tag it shows the value I want to use as the default value (10). Sort of. I can't read the selected value anymore but the default value is showing.</p>
  
  <p>I have never done anything with plunkr but will try to get an example working there and then paste a link to that in here.</p>
