Setup

There are 2 ways to initialise the component.

Automatic

Add data-ecl-auto-init="Accordion" attribute to component's markup:

<div class="ecl-accordion" data-ecl-accordion data-ecl-auto-init="Accordion">
  ...
</div>

Use the ECL library's autoInit() (ECL.autoInit()) when your page is ready or other custom event you want to hook onto.

Manual

Get target element, create an instance and invoke init().

Given you have 1 element with an attribute data-ecl-accordion on the page:

var elt = document.querySelector('[data-ecl-accordion]');
var accordion = new ECL.Accordion(elt);
accordion.init();

Retrieve an existing instance

If an existing instance needs to be updated, it can be retrieved this way:

var elt = document.querySelector('[data-ecl-accordion]');
var instance = ECL.components.get(elt);

To update an existing instance, you can run destroy() and init() on this instance, like this:

instance.destroy();
instance.init();
