javascript - Using anchor tags in react-router 4

Question

I want the page to scroll down to my anchor tags when a user navigates to it through an anchor link.

I'm using react-router 4 and I've defined things as follows:

navbar:

export default (props) => {
  const { 
    updateModal,
    updateRoute,
  } = props
  return(
    <Navbar fluid collapseOnSelect>
      <Nav>
        <NavDropdown eventKey="4" title="Solutions" id="nav-dropdown" noCaret>
          <MenuItem eventKey="4.1">
             <Link to='/solution#ipos'>TESTING ANCHOR</Link>
          </MenuItem>
...

some route:

export default class extends Component {
  constructor() {
    super()
    this.state = {
      isLoading: true
    }
  }
  render() {
    return (
      <Grid className='solutions' fluid>
       <Row className='someClass'>
        <div>
          <h2><a href='ipos' id='ipos'>Ipos morna santos paros</a></h2>
          ...

I can see the hash anchor tag in the url and in my redux store when I click on the anchor link in the navebar, and it indeed navigates to the new route, but it doesn't scroll down to the tag itself.

Is it up to me to create the scroll function or how is it supposed to work exactly?

To scroll down to your anchor tags, you need to install React Router Hash Link, with:

npm install --save react-router-hash-link

then import Hash Link:

import { HashLink as Link } from 'react-router-hash-link';

and then use Hash Link, for example:

<Link to="/pathLink#yourAnchorTag">Your link text</Link>

and at the destination component, for example:

<div id= "yourAnchorTag">
      <p>Linked to here<p>
</div>
