title: How to handle multiple routers in react
body: <p>Let say we have a web application. It has usually many views, like index page, admin panel, help page, contact etc. I handle them using react-router-dom in the main index.js and it just works fine.</p>
  
  <p>However now I faced problem with developing admin panel. It is one of the routes supported by the index.js router, but it contains its own menu with all actions available for admin.</p>
  
  <p>How should I handle this, to only replace the content I need in the admin panel (admin actions menu stays), but not the whole content as I do from index.js router?</p>
  
  <p>I tried to use the  in the admin panel place for content replacement, but it either says too much recursion (If I duplicated the route for admin panel itself) or simply does not work saying nothing.</p>
  
  <p>I'm react newbie and I don't even know how to call this problem.</p>
  
  <p>Thanks for suggestions.</p>
