How to display content in popup?

To display content in popup on button click, you have to follow 2 simple steps:

Create button shortcode:

[button title="Button" link="#your-custom-id" target="_blank" class="" download="" rel="lightbox" onclick=""]
Put the content below into any place where using raw html is allowed, ex. Column:

<div id="your-custom-id" style="display: none;">CONTENT HERE</div>

Important!

Please make sure, both, link attribute in button shortcode and div ID has exactly the same name and does not contain any special characters nor empty spaces. Otherwise, it will not work.
