Install

Package Managers

Using npm:

npm install metismenujs

Using yarn:

yarn add metismenujs

Using pnpm:

pnpm add metismenujs

Once the package is installed, you can import the library using import or require approach:

// recommended approach
import { MetisMenu } from 'metismenujs';

// You can also use the default export
import MetisMenu from 'metismenujs';

If you use require for importing, only default export is available:

const MetisMenu = require('metismenujs');

Note CommonJS usage In order to gain the TypeScript typings (for intellisense / autocomplete) while using CommonJS imports with require(), add the following to your tsconfig.json:

{
  "compilerOptions": {
    "moduleResolution": "NodeNext"
  }
}

unpkg :

<link rel="stylesheet" href="https://unpkg.com/metismenujs/dist/metismenujs.min.css">

Using Vite, Astro etc.

import 'metismenujs/style';

or sass source file

import 'metismenujs/sass';

Add class metismenu to unordered list

<ul class="metismenu" id="menu">

</ul>

Make expand/collapse controls accessible

Be sure to add aria-expanded to the element a. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible element is closed by default, it should have a value of aria-expanded="false". If you've set the collapsible element's parent li element to be open by default using the active class, set aria-expanded="true" on the control instead. The plugin will automatically toggle this attribute based on whether or not the collapsible element has been opened or closed.

<ul class="metismenu" id="menu">
  <li class="mm-active">
    <a href="#" aria-expanded="true">Menu 1</a>
    <ul>
    ...
    </ul>
  </li>
  <li>
    <a href="#" aria-expanded="false">Menu 2</a>
    <ul>
    ...
    </ul>
  </li>
  ...
  </ul>

Arrow Options

add has-arrow class to a element

<ul class="metismenu" id="menu">
<li class="mm-active">
  <a class="has-arrow" href="#" aria-expanded="true">Menu 1</a>
  <ul>
  ...
  </ul>
</li>
<li>
  <a class="has-arrow" href="#" aria-expanded="false">Menu 2</a>
  <ul>
  ...
  </ul>
</li>
...
</ul>

Call the plugin:

  new MetisMenu("#menu");
  // or
  MetisMenu.attach('#menu');

Stopping list opening on certain elements

Setting aria-disabled="true" in the <a> element as shown will stop metisMenu opening the menu for that particular list. This can be changed dynamically and will be obeyed correctly:

<a href="#" aria-expanded="false" aria-disabled="true">List 1</a>
