title: yield doesn't work in section Laravel Blade
body: <p>I have the site with the structure like:</p>
  
  <p>First: <code>master.blade.php</code> : this contain <code>section('content')</code></p>
  
  <pre><code>&lt;body&gt;
     @include('partial.header')
     @yield('content')
     @include('partial.footer')
  &lt;/body&gt;
  </code></pre>
  
  <p>Second <code>index.blade.php</code> : contain <code>section('content')</code>.</p>
  
  <pre><code>@extends('layouts.master')
  @section('content')
  &lt;div id="container"&gt;
     &lt;div id="news"&gt;
        @yield('news')
     &lt;/div&gt;
     &lt;div id="apartment"&gt;
        @yield('apartment')
     &lt;/div&gt;
  &lt;/div&gt; &lt;!-- ./container --&gt;
  @endsection
  </code></pre>
  
  <p>Third: <code>news.blade.php</code> : this simple to show all <code>news</code></p>
  
  <pre><code>@foreach($posts as $post)
  @endforeach
  </code></pre>
  
  <p>Final file: <code>apartment.blade.php</code> : this simple to show all <code>apartment</code>.</p>
  
  <pre><code>@foreach($apartments as $apartment)
  @endforeach
  </code></pre>
  
  <p>My route direct to <code>master.blade.php</code>.
  My question is:</p>
  
  <ol>
  <li><p>When I include <code>news</code> with <code>@yield('news')</code> in <code>index.blade.php</code>. It shows correct all <code>news</code> in my database.
  But when I delete <code>@yield('news')</code> in <code>index.blade.php</code>. It also show <code>news</code> from my database (but it's lost css/js for that).
  Why I deleted <code>@yield('news')</code>, it's should don't show any <code>news</code> on my page?</p></li>
  <li><p>Seem Laravel Blade not support two <code>@yield</code> in <code>@section</code>. When I add only 1 row <code>@yield('news')</code> into <code>index.blade.php</code> file. It shows list news on my index page. When I continues add <code>@yield('apartment')</code>. Don't have any apartment shown on the index page. I certainly it has values when <code>foreach</code> to get data. I also test with HTML statics but don't have anything changes.</p></li>
