title: Set orientation horizontal to items inside menu in a NavigationView
body: <p>I have a NavigationView that has an <code>app:headerLayout</code> and an <code>app:menu</code> that has three groups of items. One of this groups is made for social media:</p>
  
  <pre><code>    &lt;menu&gt;
          &lt;item
              android:id="@+id/nav_facebook"
              android:icon="@drawable/ic_facebook"
              android:title="@string/nav_drawer_facebook" /&gt;
          &lt;item
              android:id="@+id/nav_twitter"
              android:icon="@drawable/ic_twitter"
              android:title="@string/nav_drawer_twitter" /&gt;
          &lt;item
              android:id="@+id/nav_instagram"
              android:icon="@drawable/ic_instagram"
              android:title="@string/nav_drawer_instagram" /&gt;
          &lt;item
              android:id="@+id/nav_google_plus"
              android:icon="@drawable/ic_google"
              android:title="@string/nav_drawer_googleplus" /&gt;
          &lt;item
              android:id="@+id/nav_share"
              android:icon="@drawable/ic_menu_share"
              android:title="@string/nav_drawer_share" /&gt;
      &lt;/menu&gt;
  </code></pre>
  
  <p>So my question is if there is any way to make the orientation of this menu horizontal:</p>
  
  <p>At this moment it looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/7nEBd.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/7nEBd.png" alt="enter image description here"></a></p>
  
  <p>But I would like it to look like this:</p>
  
  <p><a href="https://i.stack.imgur.com/MLoKH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/MLoKH.png" alt="enter image description here"></a></p>
  
  <p>I would like to show the icons next to the other to safe some space. I know I could achieve this doing a custom layout but I would like to know if there is a way to do this with the <code>app:menu</code>.</p>
  
  <p>Any help would be appreciated. Thanxs in advance.</p>
