title: Have default selected value in Angular 5's Material Autocomplete?
body: <p>I need to have a default value selected for my autocomplete function. I can't seem to find any documentation or property like "selected" for mat-option. Thank you.</p>
  
  <p>Code:</p>
  
  <pre><code>&lt;mat-autocomplete #auto="matAutocomplete"&gt;
     &lt;mat-option *ngFor="let srd2 of stockreqDetailItemList" [value]="srd2.itemCode"&gt;
        {{srd2.itemCode}} &amp;nbsp; {{srd2.itemName}}
     &lt;/mat-option&gt;
  &lt;/mat-autocomplete&gt;
  </code></pre>
