How can I make the social buttons (under FOLLOW US) appear just like the showcase sidebar plugin? I know I might have to program it, I just need to know what would be the overall process (if you can help me I’d appreciate it)
Thank you for your question.
Yes you are right. To achieve this, you have to develop custom code in the child theme of Jevelin theme.
Developing custom code for custom functionality is beyond the scope of support that we provide here. Please see https://themeforest.net/item/jevelin-multipurpose-premium-responsive-wordpress-theme/14728833/support
If you are not a developer then you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5
Alternatively you can try using following plugins to display social icons in floating bar.
