Display Singular Chapter as a popup

To clarify my question.

I want the lightbox method used when I use shortcode to display module content. It seems like shortcode of a module content only allows for embedd with iframe.

I added the following javascript below the cluevo chapter shortcode for the desired effect.

<script>
var chapter = 2; // keep module
var x = document.getElementsByClassName(“cluevo-content”);

for (var i = 0; i < x.length; i++) {
if (i != chapter -1) {
x[i].style.display = “none”;
}
}
</script>
