Q: React native - React Navigation for multiple routes I am wondering is there any way to make StackNavigator inside TabNavigator with react-navigation, Right now I have TabNavigator like that in Router.js. I want app inside Add.js (Add screen) to make StackNavigator inside ListItem. Every element of ListItem Should get user to other screen. So If I press first option it should get me to "AddCalendarEvent" etc. Like you see in Add.js file on addList constant
Router.js
import React from 'react';
    import {
        AppRegistry,
        Text,
        View,
        Button
    } from 'react-native';
    import {StackNavigator, TabNavigator} from 'react-navigation';

    import FontAwesomeIcon from 'react-native-vector-icons/FontAwesome';
    import EntypoIcon from 'react-native-vector-icons/Entypo';

    import Login from './Login';
    import Menu from './Menu';
    import Desktop from './Desktop';
    import Notifications from './Notifications';
    import Today from './Today';
    import Add from './Add';

    const onClickNavigation = StackNavigator({
        Login: {screen: Login}
    });

    const estimobileapplication = TabNavigator({
        Add: {
            screen: Add, navigationOptions: {
                title: 'Dodaj',
                label: 'Dodaj',
                tabBarIcon: ({tintColor}) => (<FontAwesomeIcon name="plus-circle" size={24} color="#666"/>)
            }
        },
        Desktop: {
            screen: Desktop, navigationOptions: {
                title: 'Pulpit',
                label: 'Pulpit',
                tabBarIcon: ({tintColor}) => (<FontAwesomeIcon name="th-large" size={24} color="#666"/>)
            }
        },
        Notifications: {
            screen: Notifications, navigationOptions: {
                title: 'Powiadomienia',
                label: 'Powiadomienia',
                tabBarIcon: ({tintColor}) => (<FontAwesomeIcon name="envelope" size={24} color="#666"/>)
            }
        },
        Today: {
            screen: Today, navigationOptions: {
                title: 'Na dziś',
                label: 'Na dziś',
                tabBarIcon: ({tintColor}) => (<FontAwesomeIcon name="check-square" size={24} color="#666"/>)
            }
        },
        Menu: {
            screen: Menu, navigationOptions: {
                title: 'Menu',
                label: 'Menu',
                tabBarIcon: ({tintColor}) => (<EntypoIcon name="menu" size={24} color="#666"/>),
            }
        }

A: According tho the react navigation docs you can nest as many navigators as you need. Just instead of defining a component for your tab in "screen", define a StackNavigator. This way, it will display the first component that your StakNavigator Shows. 
Then in each item you define a navigate() to the next screen you need (I assume is the same screen for every item in the list) and pass the required data as a prop.
