title: Navigation Drawer: Add Titles to Groups, Not Items
body: <p>I have a standard Navigation Drawer, pre-created by Android Studio and want to populate it with number of groups. I started with this:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
      &lt;group android:checkableBehavior="single"&gt;
          &lt;item
              android:id="@+id/nav_mode_person"
              android:icon="@drawable/ic_person_black_24dp"
              android:title="Person" /&gt;
          &lt;item
              android:id="@+id/nav_mode_group"
              android:icon="@drawable/ic_group_black_24dp"
              android:title="Community" /&gt;
      &lt;/group&gt;
  
      &lt;item android:title="Communicate"&gt;
          &lt;menu&gt;
              &lt;item
                  android:id="@+id/nav_share"
                  android:icon="@drawable/ic_menu_share"
                  android:title="Share" /&gt;
              &lt;item
                  android:id="@+id/nav_send"
                  android:icon="@drawable/ic_menu_send"
                  android:title="Send" /&gt;
          &lt;/menu&gt;
      &lt;/item&gt;
  
  &lt;/menu&gt;
  </code></pre>
  
  <p>But what I didn't get is if it even possible to give each group a title? I mean there is an <code>android:title</code> option available for <code>&lt;item&gt;</code>s, but it is unavailable for <code>&lt;group&gt;</code>s and if I try to wrap groups around items, what I get is a messy entries behavior.</p>
  
  <p>I read through Google's design guideline on Navigation Drawer, but missed the point if groups should have its own names or they should not. Here is a picture of what I want to achieve:</p>

  <p>Is it possible without adding random <code>&lt;TextView&gt;</code>s? By the way, I want to do it via XML, not programmatically.</p>
