JavaScript How to replace one React Component with another OnClick? replace react component,react replace component on click,react replace

I have a "sign up" button. When it is clicked, I would like for it to render a new component, called "SignUp". I would like for the new component to replace the "sign up" button.

Currently, I am using setState so that when the button is clicked, a new component is rendered. However, the button is not being replaced, the "SignUp" component is just rendered beside the button. What may be a good approach for me to replace the button with the new component being rendered?

I have provided my code below: 

  export default class SignUpSignIn extends Component {

  constructor() {
     super();

     this.state = {
       clicked: false
     };

     this.handleClick = this.handleClick.bind(this);
   }

  handleClick() {
    this.setState({
      clicked: true
    });
  }

  render () {

    return (
    <div id="SignUpSignInDiv">

      <Col md="12" sm="12" xs="12" className="text-center">

        <div onClick={this.handleClick}>

          {this.state.clicked ? <SignUp /> : null}

        <Button id="SignUpButton" color="primary"> Sign Up </Button>

        </div>

       </Col>

    </div>
  )

  }
}

Well, you're not rendering both components conditionally, only the SignUp. Instead of having null in your ternary, render the sign in button when state.clicked === false:

render () {
  return (
    <div id="SignUpSignInDiv">
      <Col md="12" sm="12" xs="12" className="text-center">
        {this.state.clicked ? (
          <SignUp />
        ) : (
          <Button id="SignUpButton" color="primary" onClick={this.handleClick}> Sign Up </Button>
        )}
       </Col>
    </div>
  )
}
