## Install
### Package Managers
Using [npm](https://www.npmjs.com/):
```bash
npm install metismenujs
```
Using [yarn](https://yarnpkg.com):
```sh
yarn add metismenujs
```
Using [pnpm](https://pnpm.io/):
```sh
pnpm add metismenujs
```
Once the package is installed, you can import the library using `import` or `require` approach:
```js
// recommended approach
import { MetisMenu } from 'metismenujs';
```
```js
// You can also use the default export
import MetisMenu from 'metismenujs';
```
If you use `require` for importing, **only default export is available**:
```js
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`:
```json
{
"compilerOptions": {
"moduleResolution": "NodeNext"
}
}
```

Ready to use files are located in the `dist` directory.
## Usage
1. Include metismenujs StyleSheet
### Using CDN
[jsDelivr](https://www.jsdelivr.com/) :
```html
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/metismenujs/dist/metismenujs.min.css">
```
[unpkg](https://unpkg.com/) :
```html
<link rel="stylesheet" href="https://unpkg.com/metismenujs/dist/metismenujs.min.css">
```
### Using [Vite](https://vitejs.dev/), [Astro](https://astro.build/) etc.
```js
import 'metismenujs/style';
```
or sass source file
```js
import 'metismenujs/sass';
```
2. Add class `metismenu` to unordered list
```html
<ul class="metismenu" id="menu">
</ul>
```
3. 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.
```html
<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>
```
4. Arrow Options
> add `has-arrow` class to `a` element
```html
<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>
```
5. Call the plugin:
```javascript
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:
```html
<a href="#" aria-expanded="false" aria-disabled="true">List 1</a>
```
## Options
| Option | Type | Default | Description | Example |
| --- | --- | --- | --- | --- |
| toggle | Boolean | true | For auto collapse support. | `new MetisMenu("#menu", { toggle: false });` |
| triggerElement | css selector | a | | `new MetisMenu("#menu", { triggerElement: '.nav-link' });` |
| parentTrigger | css selector | li | | `new MetisMenu("#menu", { parentTrigger: '.nav-item' });` |
| subMenu | css selector | ul | | `new MetisMenu("#menu", { subMenu: '.nav.flex-column' });` |
## API
