Is there any other work around for triggering? I'm using the Divi theme and there is this Fullwidth Header Module and it has two buttons. But I can only assign CSS classes and id to the entire module but not for each button specifically. I'm trying to find a way to use those buttons for the popup trigger anyway... Do you see any option?
Eg., http://wenetwork.wpengine.com/buchung/ the left Login button
