Thank you!

LOVE IT! Works even better than advertised, here’s why: I am using the Enfold theme, which incorporates the Avia Layout builder, and have found that if I turn on the Custom CSS Classes within Avia Layout builder, I can use pop up everywhere, not just in menus. I am using them for buttons, for example, even though the buttons are built with shortcode that only accepts the URL, none of the other alligator shortcode elements. If I make the button have “mpopup” class, bingo, it works perfectly.

(The only thing I’ve ever wished was there was a way to make the pop up window feel less like a browser window and more like a lightbox, with a nice big “X” at the top right to close it. Perhaps soon!)
