Usage

  1. Include metismenujs StyleSheet

    <link rel="stylesheet" href="https://unpkg.com/metismenujs/dist/metismenujs.min.css">
    <!-- OR -->  
    <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/metismenujs/dist/metismenujs.min.css">
  2. Include metismenujs plugin's code

    <script src="https://unpkg.com/metismenujs/dist/metismenujs.min.js"></script>
    <!-- OR -->
    <script src="https://cdn.jsdelivr.net/npm/metismenujs/dist/metismenujs.min.js"></script>
  3. Add class metismenu to unordered list

    <ul class="metismenu" id="menu">
            
    </ul>
  4. 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>
  5. 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>
  6. 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>
