Question

MODX

Hello! Tell me, I'm making a gallery on MOD X REVO + fancybox
According to this lesson LINK TO THE LESSON , everything works, but here's the problem, I don't understand how to make it open not in a new window, but in a standard fancybox window when you click on the album cover and load it there photos from this album

Here in such a window, and on the right, by default, there is already a list of all the pictures in this album
