Tks for you help but this approach doesn’t work in a more complex environment.
It’s enough to add a div in whithin and it fails (see below) and in my real environment I’ve many divs or other intermediate objects.
Why we don’t see it in page elements if not checked ?
Tks
<section id=”check-box”>
<div>
<p>Checkboxes allow the user to select multiple options from a set.</p><br />
<p>If you have multiple options appearing in a list, you can preserve space by using checkboxes instead of on/off switches.</p><br />
<p>If you have a single option, avoid using a checkbox and use an on/off switch instead.</p><br />
</div>

<form>
<div>
<div class=”check-box-container-light”>
<input name=”C0″ type=”hidden”/>
<div>
<smart-check-box checked onChange=”applica(this)” name=”C1″></smart-check-box>
<smart-check-box name=”C2″></smart-check-box>
</div>

</form>
</section>
