# Modal

The Modal module allows to easily display content in a dialog window.


This guide is referring to GrapesJS v0.17.26 or higher

# Basic usage

You can easily display your content by calling a single API call.

// Init editor
const editor = grapesjs.init({ ... });
// Open modal
const openModal = () => {
        title: 'My title', // string | HTMLElement
        content: 'My content', // string | HTMLElement
// Create a simple custom button that will open the modal
    <button onclick="openModal()">Open Modal</button>

# Using API

By using other available APIs you have full control of the modal (eg. updating content/title, closing the modal, etc.).

Here are a few examples:

const { Modal } = editor;

// Close the modal

// Check if the modal is open

// Update title
Modal.setTitle('New title');

// Update content
Modal.setContent('New content');

// Execute one-time callback on modal close
Modal.onceClose(() => {
 console.log('My last modal is closed');

# Customization

The modal can be fully customized and you have different available options. The fastest and the easiest one is to use your specific CSS for the modal element. With a few lines of CSS your modal can be completely adapted to your choices.

.gjs-mdl-dialog {
    background-color: white;
    color: #333;

In case you have to customize a specific modal differently, you can rely on your custom class attributes.

    title: 'My title',
    content: 'My content',
    attributes: {
        class: 'my-small-modal',
.my-small-modal .gjs-mdl-dialog {
    max-width: 300px;


Your custom CSS has to be loaded after the GrapesJS one.

# Custom Modal

For more advanced usage, you can completely replace the default modal with one of your own. All you have to do is to indicate the editor your intent to use a custom modal and then subscribe to the modal event that will give you all the information on any requested change.

const editor = grapesjs.init({
    // ...
    modal: { custom: true },

editor.on('modal', props => {
    // The `props` will contain all the information you need in order to update your custom modal.
    // props.open (boolean) - Indicates if the modal should be open
    // props.title (Node) - Modal title
    // props.content (Node) - Modal content
    // props.attributes (Object) - Modal custom attributes (eg. class)
    // props.close (Function) - A callback to use when you want to close the modal programmatically

    // Here you would put the logic to control your modal.

Here an example of using the Bootstrap modal.
