Hello,
Thanks for your message. The screen shot you linked does not show our plugin VikRentCar. That’s probably a different plugin.
Moreover, Options/Extras are only available in the Pro/commercial version of our plugin. If you are using such version of our plugin VikRentCar, then we suggest getting in touch with our team through our website.
Lastly, unlimited kilometres with our plugin can be advertised without using the Options/Extras, but rather through the attributes of your rate plans (types of price). The rate plans in VikRentCar support custom attributes, such as “Km included”, and then by using the page “Fares Table”, you can specify the number of Km included for every day of rent, where from 3 days onwards you should simply type in “Unlimited”. This information will then be displayed in the front-end booking process.
Please make sure to be using our plugin VikRentCar, because as we said, your screen shot shows a different software.
We hope this helps!
The VikWP Team
