Magento 2 - Come creare una pagina FAQ con la fisarmonica

Voglio creare una pagina FAQ con il widget Accordion ( http://devdocs.magento.com/guides/v2.0/javascript-dev-guide/widgets/widget_accordion.html ).

È possibile usarlo su una pagina CMS?

È possibile. Se vuoi usare

data-mage-init

Quindi lo fai in questo modo:

<div id="element" data-mage-init='{"accordion":{"openedState": "active", "collapsible": true, "active": false, "multipleCollapsible": true}}'>
    <div data-role="collapsible">
        <div data-role="trigger">
            <span>Title 1</span>
        </div>
    </div>
    <div data-role="content">Content 1</div>

    <div data-role="collapsible">
        <div data-role="trigger">
            <span>Title 2</span>
        </div>
    </div>
    <div data-role="content">Content 2</div>

    <div data-role="collapsible">
        <div data-role="trigger">
            <span>Title 3</span>
        </div>
    </div>
    <div data-role="content">Content 3</div>
</div>

Questo funziona per me:

<div data-mage-init='{"accordion":{"openedState": "active", "collapsible": true, "active": false, "multipleCollapsible": false}}'>
    <div data-role="collapsible">
        <div data-role="trigger">
            Title 1
        </div>
    </div>
    <div data-role="content">
        <p>
            Content 1 bla bla bla.
        </p>
    </div>
    <div data-role="collapsible">
        <div data-role="trigger">
            Title 2
        </div>
    </div>
    <div data-role="content">
        <p>
            Content 2 bla bla bla.
        </p>
    </div>
</div>

<div id="element" data-mage-init='{"accordion":{"openedState": "active", "collapsible": true, "active": false, "multipleCollapsible": true}}'>
<button class="accordion" data-role="collapsible">Section 1</button>
<div class="panel" data-role="content">
    <p>Lorem ipsum...</p>
</div>

<button class="accordion" data-role="collapsible">Section 2</button>
<div class="panel" data-role="content">
    <p>Lorem ipsum...</p>
</div>

<button class="accordion" data-role="collapsible">Section 3</button>
<div class="panel" data-role="content">
    <p>Lorem ipsum...</p>
</div>
