The theme initially was developed to be responsive and there is no option to disable it i accordance to your specific needs and these changes you are seeking require custom work. Unfortunately we do not provide our customers with any custom work due to our policy,therefore we do not provide any instructions or files list for implementing customization you are seeking. We only do Support for our products if there are some issues in work, or some elements cause issues, etc.
In case you need to make some customizations you could try to figure this out on your own, which needs some skills in coding and programming.
In case if you believe our theme misses enough custom options to fully meet your needs you could involve/ask for help a third part developer to customize the theme the way you personally like.
Thanks for understanding and sorry for any inconveniences!
Our demo website is working fine on all devices and all elements are clickable so it could be caused specifically on your website due to customization you added. Also please be advised your support period is expired and we would recommend you to renew it for getting further assistance from our team. You can renew the support in your themeforest account in the products section. Thank you and have a great day!
