title: Is is possible to render a normal template html.erb template with active admin?
body: <p>I have a custom page in my admin built with active admin:</p>
  
  <p>In <strong>app/admin/stats.rb</strong>:</p>
  
  <pre><code>ActiveAdmin.register_page 'Stats' do
  
    controller do
  
      def index
        @foo = 'bar'
      end
    end
  end
  </code></pre>
  
  <p>And in <strong>app/views/admin/stats/index.html.erb</strong>:</p>
  
  <pre><code>&lt;h1&gt; Admin stats&lt;/h1&gt;
  &lt;p&gt;&lt;%= @foo %&gt;&lt;/p&gt;
  </code></pre>
  
  <p>When I go to /admin/stats, I see my page, but without the normal admin layout (like on the dashboard page)</p>
  
  <p>How can I decorate my page with the default layout ?</p>
  
  <hr>
  
  <p>I've tried:</p>
  
  <pre><code>ActiveAdmin.register_page 'Stats' do
  
    content do
      'foobar'
    end
  
    controller do
  
      def index
        @foo = 'bar'
      end
    end
  end
  </code></pre>
  
  <p>But this doesn't change anything. Still my stat page with no layout. Any ideas ?</p>
