Icons

Use Font Awesome Icons to create alerts with icons. Depending on your icons and content, you may want to add more utilities or custom styles.

        
            
            <div class="alert" role="alert" data-mdb-color="primary" data-mdb-alert-init>

            initMDB({ Alert });
          
        
    

Additional Content

Alerts can contain additional elements like headings, paragraphs and dividers.

        
            
            <div class="alert" role="alert" data-mdb-color="success" data-mdb-alert-init>
              <h4 class="alert-heading">Well done!</h4>
              <p>
                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.
              </p>
              <hr />
              <p class="mb-0">
                Whenever you need to, be sure to use margin utilities to keep things nice and tidy.
              </p>
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";

            initMDB({ Alert });
          
        
    

Dismissing

Using the alert JavaScript plugin, it’s possible to dismiss any alert inline. Here’s how:

  • Be sure you’ve loaded the alert plugin, or the compiled Bootstrap JavaScript.
  • Add data-mdb-alert-init attribute.
  • Add a close button and the .alert-dismissible class, which adds extra padding to the right of the alert and positions the close button.
  • On the close button, add the data-mdb-dismiss="alert" attribute, which triggers the JavaScript functionality. Be sure to use the button element with it for proper behavior across all devices.
  • To animate alerts when dismissing them, be sure to add the .fade and .show classes.

You can see this in action with a live demo:

        
            
            <div class="alert alert-dismissible fade show" role="alert" data-mdb-alert-init data-mdb-color="warning">
              <strong>Holy guacamole!</strong> You should check in on some of those fields below.
              <button type="button" class="btn-close" data-mdb-dismiss="alert" aria-label="Close"></button>
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";

            initMDB({ Alert });
          
        
    

Show

You can manually show alert using show() method.

        
            
            <div class="alert fade" id="show-example" data-mdb-hidden="true" role="alert" data-mdb-alert-init data-mdb-color="primary">
              Hidden alert!
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
            initMDB({ Alert });

            Alert.getInstance(document.getElementById('show-example')).show();
          
        
    
        
            
            mdb.Alert.getInstance(document.getElementById('show-example')).show();
          
        
    

Hide

You can manually hide alert using hide() method.

        
            
            <div class="alert fade show mt-3" id="hide-example" role="alert" data-mdb-alert-init data-mdb-color="primary">
              Hide me!
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
            initMDB({ Alert });

            Alert.getInstance(document.getElementById('hide-example')).hide();
          
        
    
        
            
            mdb.Alert.getInstance(document.getElementById('hide-example')).hide();
          
        
    

Placement

You can set the position of every alert using the data-mdb-position attribute.

Select horizontal / vertical alignment

Current position: top-right
        
            
            <div
              class="alert fade mt-3"
              id="placement-example"
              data-mdb-position="top-right"
              data-mdb-hidden="true"
              data-mdb-width="25%"
              role="alert"
              data-mdb-alert-init
              data-mdb-color="primary"
            >
              Show me wherever you want!
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
            initMDB({ Alert });
            
            Alert.getInstance(document.getElementById('placement-example')).show();
          
        
    
        
            
            mdb.Alert.getInstance(document.getElementById('placement-example')).show();
          
        
    

Container

You can display an alert anywhere. Just put it in your target element and fill the data-mdb-container attribute with id or class of parent.

        
            
            <div
              class="alert fade"
              id="container-example"
              role="alert"
              data-mdb-alert-init
              data-mdb-container="#parent-container-example"
              data-mdb-color="primary"
            >
              Hello from parent element!
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
    
            initMDB({ Alert });

            Alert.getInstance(document.getElementById('container-example')).show();
          
        
    
        
            
            mdb.Alert.getInstance(document.getElementById('container-example')).show();
          
        
    

Offset

You can set offset of your alert using a data-mdb-offset tag.

        
            
            <div
              class="alert fade"
              id="offset-example"
              data-mdb-hidden="true"
              data-mdb-offset="100"
              role="alert"
              data-mdb-alert-init
              data-mdb-color="primary"
            >
              Offset: 100px
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
            initMDB({ Alert });

            Alert.getInstance(document.getElementById('offset-example')).show();
          
        
    
        
            
            mdb.Alert.getInstance(document.getElementById('offset-example')).show();
          
        
    

Stacking

You can turn on stacking your alerts using the data-mdb-stacking attribute.

        
            
            <div class="container text-center">
              <button type="button" class="btn btn-primary" id="stacking-trigger-example" data-mdb-ripple-init >
                Show notification
              </button>
            </div>
          
        
    
        
            
            // Initialization for ES Users
            import { Alert, initMDB } from "mdb-ui-kit";
            initMDB({ Alert });

            let alertCount = 0;

            function* colorGenerator(i) {
              const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];

              while (true) {
                yield colors[i];

                i++;

                if (i > colors.length - 1) {
                  i = 0;
                }
              }
            }

            const colorIterator = colorGenerator(0);

            document.getElementById('stacking-trigger-example').addEventListener('click', () => {
              alertCount++;
              color = colorIterator.next().value;

              const alert = document.createElement('div');
              alert.innerHTML = `
                <div class="d-flex justify-content-between">
                  <p class="mb-0"><strong>${alertCount}.</strong> Stacking alerts</p>
                  <button type="button" class="btn-close" data-mdb-dismiss="alert" aria-label="Close"></button>
                </div>
              `;
              alert.classList.add('alert', 'fade');

              document.body.appendChild(alert);

              const alertInstance = new Alert(alert, {
                color,
                stacking: true,
                hidden: true,
                width: '450px',
                position: 'bottom-right',
                autohide: true,
                delay: 5000,
              });

              alertInstance.show();
            });
          
        
    
        
            
            let alertCount = 0;

            function* colorGenerator(i) {
              const colors = ['primary', 'warning', 'info', 'success', 'secondary', 'danger', 'light'];

              while (true) {
                yield colors[i];

                i++;

                if (i > colors.length - 1) {
                  i = 0;
                }
              }
            }

            const colorIterator = colorGenerator(0);

            document.getElementById('stacking-trigger-example').addEventListener('click', () => {
              alertCount++;
              color = colorIterator.next().value;

              const alert = document.createElement('div');
              alert.innerHTML = `
                <div class="d-flex justify-content-between">
                  <p class="mb-0"><strong>${alertCount}.</strong> Stacking alerts</p>
                  <button type="button" class="btn-close" data-mdb-dismiss="alert" aria-label="Close"></button>
                </div>
              `;
              alert.classList.add('alert', 'fade');

              document.body.appendChild(alert);

              const alertInstance = new mdb.Alert(alert, {
                color,

            });
          
        
    

Stacking - Container

You can also stack alerts inside the container

        
            
            <div class="container text-center" id="parent-stacking-container-example">
              <button type="button" class="btn btn-primary mb-5" id="stacking-container-trigger-example" data-mdb-ripple-init >

Alerts - API


Import

Importing components depends on how your application works. If you intend to use the MDBootstrap ES format, you must first import the component and then initialize it with the initMDB method. If you are going to use the UMD format, just import the mdb-ui-kit package.

        
            
          import { Alert, initMDB } from "mdb-ui-kit";
          
          initMDB({ Alert });
        
        
    
        
            
          import "mdb-ui-kit"
        
        
    

Usage

Via data attributes

Using the Alert component doesn't require any additional JavaScript code - simply add data-mdb-alert-init attribute to .alert and use other data attributes to set all options. For ES format, you must first import and call the initMDB method.

        
            
          <div class="alert alert-primary fade show" id="example" data-mdb-alert-init data-mdb-autohide="true" data-mdb-delay="2000" role="alert">
            Example
          </div>
        
        
    
Dismiss

Dismissal can be achieved with data attributes on a button within the alert as demonstrated below:

        
            
            <button type="button" class="btn-close" data-mdb-dismiss="alert" aria-label="Close"></button>
          
        
    

or on a button outside the alert using the data-mdb-target as demonstrated below:

        
            
            <button type="button" class="btn-close" data-mdb-dismiss="alert" data-mdb-target="#my-alert" aria-label="Close"></button>
          
        
    

Via JavaScript

        
            
          const element = document.querySelector('.alert');
          new Alert(alert)
        
        
    
        
            
          const element = document.querySelector('.alert');
          new mdb.Alert(alert)
        
        
    

Via jQuery

Note: By default, MDB does not include jQuery and you have to add it to the project on your own.

        
               
          $(document).ready(() => {
            $('.example-class').alert(options);
          });
        
        
    

Options

Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-mdb-, as in data-mdb-offset="".

Name Type Default Description
position String / null null Sets the position of the alert. It can include horizontal options: top or bottom, and vertical options: left, center, or right. It can also be a combination of any horizontal and vertical values, for example, top-left
delay Number 1000 Sets the length of animation delay
autohide boolean false Alerts will hide automatically or not
width String 'unset' Sets width of alert
container String - Defines id/class of the parent element
offset Number 10 Defines offset of the element
stacking Boolean false Enables stacking alerts
appendToBody Boolean false Appends element to the end of the body
color String / null null Allows to set the color of an alert - primary | secondary | secondary | danger | warning | info | light | dark

Methods

Name Description Example
show Manually shows an alert myAlert.show()
hide Manually hides an alert myAlert.hide()
close Manually hides an alert (deletes it from DOM) myAlert.close()
dispose Removes an mdb.Alert instance myAlert.dispose()
getInstance Static method which allows you to get the alert instance associated to a DOM element. Alert.getInstance(myAlert)
getOrCreateInstance Static method which returns an alert instance associated to a DOM element or create a new one in case it wasn't initialized. Alert.getOrCreateInstance(myAlert)
update Updates options of an mdb.Alert instance myAlert.update({position: 'top-right'})
        
            
          const alertEl = document.getElementById('show-example');
          const alert = new Alert(alertEl);
          alert.show();
        
        
    
        
            
        const alertEl = document.getElementById('show-example');
        const alert = new mdb.Alert(alertEl);
        alert.show();
      
        
    

Events

Name Description
close.mdb.alert Fires immediately when the close instance method is called.
closed.mdb.alert Fired when the alert has been closed and CSS transitions have completed.
        
            
          const alert = document.getElementById('example')
          alert.addEventListener('close.mdb.alert', () => { 
            // do something
          });
        
        
    

CSS variables

As part of MDB’s evolving CSS variables approach, alerts now uses local CSS variables on .alert for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.

        
            
          // .alert
          --#{$prefix}alert-bg: transparent;
          --#{$prefix}alert-padding-x: #{$alert-padding-x};
          --#{$prefix}alert-padding-y: #{$alert-padding-y};
          --#{$prefix}alert-margin-bottom: #{$alert-margin-bottom};
