title: Display other table data from drop down list when edit
body: <p>Is that possible to get data from other table?</p>
  
  <p>Let say in create table, I get all the info from genre table and display all data in drop down list</p>
  
  <pre><code>      &lt;select name="mov_genre" id="mov_genre" class="form-control input-sm"&gt;
            &lt;option value=""&gt;类型&lt;/option&gt;
                 @foreach(App\Genre::all() as $gData)
            &lt;option value="{{$gData-&gt;gen_title}}"&gt;{{$gData-&gt;gen_title}}&lt;/option&gt;
                 @endforeach
        &lt;/select&gt;
  </code></pre>
  
  <p>In edit page, I want to display it as well but how to display it as the genre I selected when create?</p>
