Hello, PR,
Thank you for using our theme and for contacting us.
In order to make the mobile menu similar to the website as on the PCA, you will need to create a static block and then activate the custom HTML block in the mobile menu. Please read and follow the instructions written in this topic: https://www.8theme.com/topic/how-to-add-images-on-mobile-menu/
We hope this will solve your issue.
Best Regards,
8Theme’s Team
