🪟 Modally npm version

Your trusty nested modal ally

If there are many different variations of the same functionality, the rule says it's easy to make. And the same goes for web modal dialogues - they are super easy to make.

I created this web modal dialog library as a repo cause I wrote the same code for every project that required modals, over and over again throughout the years, just because it's trivial and I needed "5 minutes" to make it. It's not 5 minutes of course, it never is.

Life is short - make reusable code!




  • Simplest one yet - almost everything is automatic (or at least it should be 😅)
  • Nested - automatic detection of the order or parent, no need for additional coding
  • ESM and IIFE - use it as a module or as a script
  • HTML auto-wrapped
  • State body classes
  • Vertically centered - doesn't need to be, but it can be
  • Scroll blocking
  • Video embeddable - automatic Vimeo, Youtube and HTML Video embeds with autoplay
  • Image lightbox - automatic image lightbox
  • ESC closable
  • Hash change detection - automatic modal open on hash change
  • Infinitely customizable - go f**king wild 🎉
  • Framework agnostic - no dependencies, fully native! You can use it with jQuery if you want to, $(selector).modally(options) a plugin is available if jQuery is present if you use this library as an IIFE script.



npm i modally


yarn add modally

Use it as a module

import Modally from 'modally';

Or as an IIFE script, Modally will be available as a global class, or as a jQuery plugin if jQuery is present $(selector).modally(options)


As iife files

<script src=""></script>
<link href="" rel="stylesheet">

Or as a remote module

import Modally from '';


Modally works with IDs. You need to apply a unique ID to each modal. If you are creating a modal from an existing element, it's ID will be used. If you are creating a modal with dynamic content (advanced usage), you need to provide an ID.

// TODO: OPENING AND CLOSING MODALS target="_modal:open:modal-id" target="_modal:close:modal-id" explained // TODO: explain Modally class and the indexing of modals // TODO: Document the selector option, make a distinction between modally options and modal options

Quick Start

<div id="your-content" hidden><h1>Hello world!</h1></div>
<a href="#your-content" target="_modal"></a>
const modally = new Modally();

//turns your content into a modal, wraps it nicely

Youtube and Vimeo modals

const modally = new Modally();

//creates a video modal which looks for data-video and opens a Youtube or Vimeo embed within your modal
modally.add('your-video-modal', {video: true});
<a href="#your-video-modal" target="_modal" data-video="">Youtube</a>

<button type="button" target="_modal:open:your-video-modal" data-video="">Vimeo</button>

Image lightbox

const modally = new Modally();

//creates an image modal which looks for data-image and opens an image within your modal
modally.add('your-image-modal', {image: true});
<a href="#your-image-modal" target="_modal" data-image="" data-width="800" data-height="600">Image</a>

<a href="#your-image-modal" target="_modal" data-image="" data-width="600" data-height="800">Image 2</a>

Advanced Usage

const modally = new Modally();

document.addEventListener('modally:open:advanced-example', function(e) {
	console.log(e.detail); // Modal instance, contains template, target, element (if any), options, etc.
	console.log(; // Target element, the one that triggered the modal open. If it exists that is, otherwise it is undefined. So in the case of this example it will be the <a> element with href="#advanced-example"
	e.detail.template.querySelector('.modally-content').innerHTML = 'Hello world!';
<a href="#advanced-example" target="_modal"></a>


Property Default Accepts Description
landing document.body string selector or element where to append the modal window
disableScroll true boolean Whether to disable scrolling on the body when modal is open
scrollToTop true boolean Whether to scroll to top modal content upon opening a modal
maxWidth 'none' 'none' or number Defines maximum width of the modal window, just like max-width css property
classes '' string Additional classes to add to the modal window
verticalAlign 'middle' 'middle' or 'top' or 'bottom' Vertical orientation of the modal window, like vertical-align css property
closeParent false boolean Whether to close the parent modal window, parent window is automatically selected if a modal open is triggered within another modal
closeOthers false boolean Wether to close all other opened modals upon opening this modal
enableHashChange true boolean Whether to open a modal on hash change
closeOthersOnHashChange false boolean Whether to close all other opened modals upon opening a modal on hash change
updateHash false boolean Whether to update the hash when opening a modal. If set to true, the hash will be updated to the modal ID and the data attributes will be added to the hash as well in case of a video or image modal
video false boolean For creating a video modal
image false boolean For creating an image "lightbox" modal
autoplay true boolean Whether video modal should autoplay
template default modally template :point-down: HTML string or element Template of the modal window

Options can also be assigned via data attributes if you are creating a modal from an element. Attributes are named using the following pattern: modally-<option-name>, like so:

<div id="hello-world" modally-max-width="800" modally-vertical-align="top">
	<h1>Hello world!</h1>
const modally = new Modally();

Default template

<div class="modally-wrap">
	<div class="modally-table">
		<div class="modally-cell">
			<div class="modally-underlay modally-close"></div>
			<div class="modally" role="dialog" aria-modal="true">
				<button tabindex="1" aria-label="Close" class="modally-close modally-close-button">&times;</button>
				<div class="modally-content"></div>


Event Description
modally:added modal was created
modally:open modal is being opening
modally:opened modal is opened
modally:close modal is being closed
modally:closed modal is closed

Modally events are named using the following pattern: namespace:action where namespace is modally and action is one of the above. Or namespace:action:modal-id where modal-id is the ID of the modal that is being opened/closed or added.

All events are dispatched on the document object and contain a detail property with the modal instance.

You can listen to a specific event of a specific modal via it's ID, by creating a listener to the event name consisted of the namespace + action + modal ID, like so:

document.addEventListener('modally:open:your-modal-id', function(e) {
	console.log(e.detail); // Modal instance, contains template, target, element (if any), options, etc.

or you can tune to all events of all modals and then check for the modal ID like so:

document.addEventListener('modally:open', function(e) {
	if ( === 'your-modal-id') {
		console.log(e.detail); // Modal instance, contains template, target, element (if any), options, etc.

Events without the modal ID (namespace + action only) are dispatched on the element that is used for modal creation and becomes it's content (if it exists of course) and on template element as well.

P.S. Here is an oxymoron for you: I'm one of these people who if they have the time to make something they don't use other people's code, not to have to spend time extending it if god forbids it happens to be needed. Life's not so short now, huh?
