title: Custom navigator menu in React Native
body: <p>I'm new in React Native and have a project with a kind of menu on the right side (5 buttons) on several screens. What I want to do is to use this menu only once for the whole app with a container, and change the content of the container according to the selected button, like in Android with fragment and fragmentManager.replace... </p>
  
  <p>Screens and menu are developed but I really don't know how to mix everything properly . </p>
  
  <p>I read doc about react-navigation (<a href="https://reactnavigation.org/docs/en/custom-navigators.html" rel="nofollow noreferrer">https://reactnavigation.org/docs/en/custom-navigators.html</a>) but do not understand well everything. However I just need a kind of TabNavigator with custom Tab on the ride side.</p>
  
  <p>Please help me.</p>
