                blockOpen: false,
                checkIsMobileResolution() {
                    this.isMobile = window.matchMedia('(max-width: 768px)').matches;
                  
                }

            }
        }
    </script>
<?php endif; ?>

I’ve tried with an expression inside the click event, but it doesn’t work, any suggest?

I want the accordion to be clickable (open = !open) on mobile, and not clickable and always open on desktop.

Thanks guys!
