Hello Alvaro, 

You can create a shortcode for a specific category [ameliacatalog category=1] and then you will have right away the services from that category shown on the front-end.

These are the available shortcodes in Amelia, so you can choose the one that would best suit your business needs: 

1. For Step-by-Step Booking Wizard view:
   1. [ameliabooking] if you want to show the basic Step-by-step Booking wizard,
   2. [ameliabooking category=1] if you want to show only the services from a category with ID 1,
   3. [ameliabooking service=1] if you want to show the booking form for the service with ID 1.

   5. [ameliabooking location=1] if you want to show the booking form for the location with ID 1,
   6. [ameliabooking category=1 employee=1] if you want to show only the services from a category with ID 1 that are assigned to the employee with ID 1,
   7. [ameliabooking category=1 location=1] if you want to show only the services from a category with ID 1 that are provided on the location with ID 1,

   1. [ameliaevents] if you want to show list of all your events,
   2. [ameliaevents tag=’name’] if you want to show just the events that belongs to the same tag defined during the creation of events, where “name” will be replaced with the tag name,
   3. [ameliaevents event=1] if you want to show only the event with ID 1 without its recurring events,
   4. [ameliaevents event=1 recurring=1] if you want to show the event with ID 1 with all his recurring events.
5. Amelia Front-end Customer Panel
   1. [ameliacustomerpanel appointments=1 events=1] if you want to show both Appointments and Events,
   2. [ameliacustomerpanel events=1] if you want to show only Events,
   3. [ameliacustomerpanel appointments=1] if you want to show only Appointments in the Customer Panel.

You are welcome, Alvaro. 

No, unfortunately, that isn't possible to achieve in Amelia. 

You can only have that view with services if you show only one category at a time on your pages with the shortcode that uses the ID of a category, like I mentioned in my answer - [ameliacatalog category=1] . So, this can be only achieved if you separate the services by categories, and have separate booking forms for each category. You can't show services for all categories with skipping the first step (where a category is chosen). 

You are welcome, Alvaro.
