Storyline Articulate, Lightbox

The current version of Storyline doesn't include a way to disable the X button in a lightbox.

• I recall seeing someone post JavaScript that hides the X button. You could try searching for that. Or perhaps one of the JS experts will see your post and add it here.

Here's another option to get the control you want: Instead of lightboxing the slide, jump to it. But turn off the regular navigation elements (e.g., the Menu and the built-in navigation buttons), so the user can only interact with your custom buttons. 

Hi, Enas.

I wanted to quickly add a couple of resources related to Judy's answer above:

• Storyline 360 Lightbox Close Button (A Javascript option)
• How to Create a Custom Lightbox Effect in Storyline 360

I hope this helps!
