Setup
There are 2 ways to initialise the component.
Automatic
Add data-ecl-auto-init="Expandable" attribute to component's markup:
<div class="ecl-expandable" data-ecl-expandable data-ecl-auto-init="Expandable">
...
</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-expandable on the page:
var elt = document.querySelector('[data-ecl-expandable]');
var expandable = new ECL.Expandable(elt);
expandable.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-expandable]');
var instance = ECL.components.get(elt);
