Installation

NPM

NPM is recommended for large-scale development, since it works well with bundlers like Webpack or Rollup.

# latest stable
npm install accessible-menu

CDN

For learning/prototyping purposes you can use the latest version with:

<script src="https://cdn.jsdelivr.net/npm/accessible-menu/dist/accessible-menu.js"></script>

For production environments, it is recommend to use a specific version to avoid unforseen breaking changes:

<script src="https://cdn.jsdelivr.net/npm/accessible-menu@3.0.0/dist/accessible-menu.min.js"></script>

Usage

To use accessible-menu, you first need to make sure your menu matches the following structure:

<ul id="example-menu">
  <li><a href="/about">About</a></li>
  <li class="dropdown">
    <a href="#">Projects ▼</a>
    <ul>
      <li><a href="/projects/awesome">Awesome project</a></li>
      <li><a href="/projects/not-so-awesome">Not-so-awesome project</a></li>
    </ul>
  </li>
  <li><a href="/contact">Contact me</a></li>
</ul>

Include accessible-menu through import or bundled library in your project:

import AccessibleMenu from "accessible-menu";

or

<script src="https://cdn.jsdelivr.net/npm/accessible-menu@3.0.0/dist/accessible-menu.min.js"></script>

Once you have accessible-menu loaded, declare a new menu object.

menuElement is required for all menus, while submenuItemSelector is only required if you have submenus/dropdowns.

const menu = new AccessibleMenu.DisclosureMenu({
  menuElement: document.querySelector("#example-menu"),
  submenuItemSelector: "li.dropdown",
});

Only need one type of menu class?

Bundled versions of each menu are provided in the dist and individual exports are provided in the index.

There are also compiled ES Module versions if you don't want to use an iife!

import { DisclosureMenu } from "accessible-menu";

or

<script src="https://cdn.jsdelivr.net/npm/accessible-menu@3.0.0/dist/disclosure-menu.min.js"></script>

then

  menuElement: document.querySelector("#example-menu"),
  submenuItemSelector: "li.dropdown",
});

Bootstrap support

Looking to use this with Bootstrap? Because Bootstrap adds classes to the menu's containing element to show/hide the menu, you'll need custom open/close functions for your menu. Check out the accessible-menu-bootstrap-4 project where all that is done for you!
