When using Catalog Booking Form, clicking on a category (step 1) display Services and you have the left Side Bar to filter categories and select a Service (step 2).
I will like to have the option to also display ALL, so all services vill display.
Allso I will like a shortcode to the Catalog Booking Form, so the Catalog Booking Form open with this window (step 2) displaying all the services to select and have the Side Bar to filter category.
