title: Remove subsection and from navigation drawer submenu
body: <p>I want to remove the unwanted space created in submenu. </p>
  
  <p>Is there any possibility I can achieve it from <code>menu.xml</code> class? </p>
  
  <p>Here is my <code>navigation_drawer_menu.xml</code></p>
  
  <pre><code>&lt;menu xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  
  
  &lt;group android:checkableBehavior="single"&gt;
      &lt;item
          android:id="@+id/all"
          android:checked="true"
          android:icon="@drawable/ic_channels"
          android:title="All Channels" /&gt;
      .......
      &lt;item
          android:id="@+id/other"
          android:icon="@drawable/ic_other"
          android:title="Others" /&gt;
  
  &lt;/group&gt;
  
  &lt;item android:title=""&gt;
      &lt;menu&gt;
          &lt;item
              android:id="@+id/setting"
              android:icon="@drawable/ic_action_settings"
              android:title="Settings" /&gt;
          &lt;item
              android:id="@+id/about"
              android:icon="@drawable/ic_about"
              android:title="About" /&gt;
          &lt;item
              android:id="@+id/share"
              android:icon="@drawable/ic_share"
              android:title="Share" /&gt;
      &lt;/menu&gt;
  &lt;/item&gt;
