Additional content

Well done!

Aww yeah, you successfully read this important alert message. This example text is going to run a bit longer so that you can see how spacing within an alert works with this kind of content.

Whenever you need to, be sure to use margin utilities to keep things nice and tidy.

import React from 'react';
import { Alert } from 'reactstrap';

const Example = (props) => {
  return (
    <div>
      <Alert color="success">
        <h4 className="alert-heading">Well done!</h4>
        <p>

Dismissing

I am an alert and I can be dismissed!

import React from 'react';
import { Alert } from 'reactstrap';

class AlertExample extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      visible: true
    };

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

  onDismiss() {
    this.setState({ visible: false });
  }

  render() {
    return (
      <Alert color="info" isOpen={this.state.visible} toggle={this.onDismiss}>
        I am an alert and I can be dismissed!
      </Alert>
    );
  }
}

export default AlertExample;

Uncontrolled [disable] Alerts

For the most basic use-case an uncontrolled component can provide the functionality wanted without the need to manage/control the state of the component. UncontrolledAlert does not require isOpen nor toggle props to work.

I am an alert and I can be dismissed!

import React from 'react';
import { UncontrolledAlert } from 'reactstrap';

function AlertExample() {
  return (
    <UncontrolledAlert color="info">
      I am an alert and I can be dismissed!
    </UncontrolledAlert>
  );
}

export default AlertExample;

Alerts without fade

Fade can be disbaled using fade=false.

I am a primary alert and I can be dismissed without animating!

I am an alert and I can be dismissed without animating!

import React from 'react';
import { UncontrolledAlert } from 'reactstrap';
import Alert from '../../../src/Alert';

export class AlertFadelessExample extends React.Component {

  constructor(props) {
    super(props);

    this.state = {
      visible: true
    };

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

  onDismiss() {
    this.setState({ visible: false });
  }

  render() {
    return (
      <div>
        <Alert color="primary" isOpen={this.state.visible} toggle={this.onDismiss} fade={false}>
          I am a primary alert and I can be dismissed without animating!
        </Alert>
      </div>
    );
  }
}

export function UncontrolledAlertFadelessExample() {
  return (
    <div>
      <UncontrolledAlert color="info" fade={false}>
        I am an alert and I can be dismissed without animating!
      </UncontrolledAlert>
    </div>
  );
}
