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/accessibleMenu.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@1.1.0/dist/accessibleMenu.js"></script>

Usage

To use accessible-menu, you first need to ensure your menu follows a basic menu structure.

<menu>
    <menu-item><a>...</a></menu-item>
    <menu-item-with-dropdown>
        <dropdown-toggle />
        <dropdown-menu>
            <menu-item><a>...</a></menu-item>
            ...
        </dropdown-menu>
    </menu-item-with-dropdown>
    <menu-item><a>...</a></menu-item>
    ...
</menu>

include the root menu or bundled library in your project:

import AccessibleMenu from 'accessible-menu';

or

<script src="path/to/accessible-menu/dist/accessibleMenu.js"></script>

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

const menu = new AccessibleMenu({
    menuElement: menuDOMObject,
    menuItemSelector: "menu-item-css-selector",
    submenuItemSelector: "menu-item-with-dropdown-css-selector",
    submenuToggleSelector: "dropdown-toggle-css-selector",
    submenuSelector: "dropdown-menu-css-selector",
    openClass: "class-to-open-menus"
});

Internet Explorer and Edge Support

For both IE and older (non-chromium-based) versions of Edge support, you will either need to use the CDN option, or run your code through Babel.

If you are compiling your own code without the help of something like Babel + core-js, you will need polyfills for Array.from(), Array.includes(), and Array.find() for IE11 support.

Versioning

This project uses Semantic Versioning 2.0.0 to keep track of releases.
