Hi. This can be done with the help of the trick. SP PB has on board Magnific Popup JS. You can use it. You will need the JCE editor to be able to insert the code.
Use the following structure:
<div id="your_unique_id" class="white-popup-block mfp-hide"><div class="modal-inner-block"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Id quasi nam minus voluptatibus totam culpa! Consequatur atque ipsum suscipit doloremque?</p></div></div>
<a class="sppb-magnific-popup sppb-modal-selector" data-popup_type="inline" data-mainclass="mfp-no-margins mfp-with-zoom" href="#your_unique_id" id="your_unique_id-selector">Open popup</a>
Replace your_unique_id to your. This should be unique for each individual Popup. Insert it while in code mode, after your text.
