We think that this feature requires custom development work. In consequence, our recommendation is to hire a freelancer to do this job for you.
If you’re on a tight budget, we recommend you to require the services from Envato Studio freelancers (https://studio.envato.com/explore/websites-programming). This web platform gives you access to developers who have already experience with theme customizations, and for very competitive prices.
You're trying to setup your theme but you're experiencing errors when importing the demo content? Or you've just followed the setup guide but your website doesn't look exactly like our demo? These are common issues for which you can find easy and quick fixes.
Feel free to review our theme on Themeforest! It helps us making our products more known to new potential customers, which allow us more time to improve the quality and develop new features. #SharingIsCaring ❤️
