How to split the values passed from one field to another using calculations?

en la foto se puede ver que los valores de una lista coloco con el siguiente formato

especificaciones <br /> especificacion1 <br /> especificacion2 <br /> especificacion3

esto con el fin de separar una linea de otra

aparentemente lo separa según la foto

sin embargo a la hora de generar el documento todo se junta no se separa la linea

I have been performing some tests and I found that it's not possible to split the words on single lines, the HTML <br> tag will not work as the form builders does not allow HTML code on the settings due to security reasons. 

I have been trying to format the text with some CSS, but it did not work either. As an alternative, you may try reducing the text element's width, this way you can break the words, here is a sample code you may use: 

[data-type="control_text"] .form-html {

    width: 10%;

}

Try injecting this to your form's CSS code and see the result, you can change the "10%" value with any other one you want, this guide will help you injecting the code to your form: https://www.jotform.com/help/117-How-to-Inject-Custom-CSS-Codes

I hope this helps. 

podria explicarme mas sobre ese codigo?

I think the code is just a workaround that will reduce the text element's width. 

Let us know if you need further explanation. Thank you.
