Hi ,
Thank you for your message.
The sticky behavior is not handled by SP Page Builder itself. In your setup, the header functionality and menu behavior are managed by the template and the DJ Mega Menu extension. Since the issue occurs specifically with the menu/header behavior on mobile, this falls outside SP Page Builder’s support scope.
We recommend contacting the DJ Mega Menu component author for guidance or a solution regarding sticky behavior on mobile devices, as they can advise on compatibility and any required configuration or customization.
Thank you for your understanding.
Best regards
