Rendering part of component only on few routes

I have my application and I'm using react-router.On every route I have rendered Navbar and in the Navbar I have input field which I want to render only on two routes. How can I do it ? Is there any "If" that can I use to render part of component when route is matched ?

In your Route you will have a collection of RouteParams (match, location and history). You can use e.g. the location.pathname to conditionally render whatever you want.

Something like: 

<Router>
  <Route render={({match,location,history})=>{
    const showNavFields = location.pathname==='/your-path'
    return {
     <NavBar showNavFields={showNavFields}/>  
    }
 }}/>
 <Switch>
   <Route path="/your-path" component="AComponent"/ >
   <Route path="/your-other-path" component="AnotherComponent"/ >
 </Switch>
</Router>

We can use match.url for that.

Working code. Here we are appending route matched to router url if route is /topics/rendering

import React from "react";
import { BrowserRouter as Router, Route, Link } from "react-router-dom";

function BasicExample() {
  return (
    <Router>
      <div>
        <ul>
          <li>
            <Link to="/">Home</Link>
          </li>
          <li>
            <Link to="/topics">Topics</Link>
          </li>
        </ul>

        <hr />

        <Route exact path="/" component={Home} />
        <Route path="/topics" component={Topics} />
      </div>
    </Router>
  );
}

function Home() {
  return (
    <div>
      <h2>Home</h2>
    </div>
  );
}

function Topics({ match }) {
  return (
    <div>
      <h2>Topics</h2>
      <ul>
        <li>
          <Link to={`${match.url}/rendering`}>Rendering with React</Link>
        </li>
        <li>
          <Link to={`${match.url}/components`}>Components</Link>
        </li>
      </ul>

      <Route path={`${match.path}/:topicId`} component={Topic} />
      <Route
        exact
        path={match.path}
        render={() => <h3>Please select a topic.</h3>}
      />
    </div>
  );
}

function Topic({ match }) {
  if (match.url === '/topics/rendering') {
    return (
    <div>
      <h3>route matched {match.params.topicId}</h3>
    </div>
  )
  } else {
    return (
      <div>
        <h3>{match.params.topicId}</h3>
      </div>
    )

  }

}

export default BasicExample;
