Creating a drop down with multiple calendar

Hello, I seen in a post where someone said they can add multiple calendars in a drop down to allow for different times for a service as a solution. My question is if I make different calendars for each service then how do I add it to a drop down so each calendar has specific times for that service. The thread is below with the question.

Hi,
Yes, the two calendars is the solution but that can be made better with the commercial version, where you can add a drop-down for selecting the service and then display only one of the calendars depending of the selection made on the drop-down. Drop-down fields supports conditional rules or dependent fields, so you can select which fields to display based in the option selected in the drop-down.
This way the user will see only one calendar, the one related to the selected service.
For more info about commercial versions you can post a support ticket at https://apphourbooking.dwbooster.com/contact-us
Thank you for your interest in the plugin!
