title: How to pass a variable to ngFor with ngx-translate?
body: <p>I'm trying to iterate over a key/value json object which comes from the translation file of the ngx-translate.</p>
  
  <p>This works fine:</p>
  
  <pre><code>&lt;div *ngFor="let item of 'gallery.01.images' | translate | keyvalue"&gt;
      &lt;p&gt;{{item .key}}:{{item .value}}&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But if I want to include a variable in iterable object, it throws error below:</p>
  
  <pre><code>&lt;div *ngFor="let item of 'gallery.{{id}}.images' | translate | keyvalue"&gt;
      &lt;p&gt;{{item .key}}:{{item .value}}&lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Error</p>
  
  <pre><code>emplate parse errors: Can't bind to '*ngFor' since it isn't a known property of 'div'

      }
  }
