title: React-Native DrawerNavigator Menu on both sides
body: <p>I have a react native app with a DrawerNavigator. For the menu I have my own component. That works great.
  Now I want to add a second side menu on the right side. 
  Is it possible to have two DrawerNavigator like in the Slack App?
  This solution is not working for me: <a href="https://snack.expo.io/ry7lYempe" rel="nofollow noreferrer">https://snack.expo.io/ry7lYempe</a>
  because I don't want to have a TabController as parent. Both Drawer should be accessible in all screens.</p>
  
  <p>My code looks like this:</p>
  
  <pre><code>import React from 'react'
  import reducer from './src/reducers'
  import { DrawerNavigator } from 'react-navigation';
  import SidebarMenu from './src/components/layout/SidebarMenu'
  
  import { createStore } from 'redux';
  import { Provider } from 'react-redux';
  
  let store = createStore(reducer);
  
  import News from './src/screens/News'
  import HowTo from './src/screens/HowTo'
  
  
  export default class MyApp extends React.Component {
  
      render() {
  
          return (
              &lt;Provider store={store}&gt;
                  &lt;MainNavigator /&gt;
              &lt;/Provider&gt;
          );
      }
  }
  
  const MainNavigator = DrawerNavigator(
      {
          News: {
              path: '/news',
              screen: News
          },
          HowTo: {
              path: '/howto',
              screen: HowTo
          }
      },
      {
          initialRouteName: 'News',
          drawerPosition: 'left',
          contentComponent: SidebarMenu
      }
  );
  </code></pre>
  
  <p>Solved after updating react-navigation to the newest version.</p>
