Hi Team, I'm using the message & spa pro themes. Now, I want to add a booking feature to "Variety of Spa". At "Variety of Spa", I want to add a button "Book Now". When user click on the button, the system will display a popup which containing a calendar like Jquery Calendar. After user select an appointment, they will click on "Book Now" button on the popup and the system will show the payment section (maybe use woocommerce. If you have the better payment module, you can suggest me.). P/S: I see the theme has Book An Appointment feature but I can't get anywhere to config to active that feature.
