Hello Javier, 

Could you please write tickets in English, since none of us here is a native Spanish speaker and we are afraid that something will be misunderstood in the translation process? Thanks!

Good afternoon,
My website is a spa, and in the spa circuit service no employee is necessary.
Is it possible to have service without employees?

I get this when I translate your question. Unfortunately, something like this is not possible in Amelia. You need to have an employee and services assigned to this employee. You can create one dummy employee and assign all services to this employee, set the maximum capacities of the services to be the number of people that can be in the spa for that time slot. And you can hide the employee dropdown on the front-end if you want. 

If you have any further questions or concerns feel free to ask, 

Hello Javier, 

Try adding this custom HTML to the page where you have your Amelia shortcode: 

<style>#amelia-step-booking0 > div.am-select-service > form > div.el-form-item.am-select-employee-option {display:none}</style>

and let me know if it worked please. 

Hello Javier, 

Please send me a link to your page where you have the booking form so I can find the right selector. Thanks!

Hello Javier, 

Glad to hear that! Thank you for letting me know. 

If you have any other questions or concerns feel free to open a new ticket and we will gladly help,
