Input Mask: Configure field with customized format

Y como consulta adicional, cómo es posible configurar un campo que obligatoriamente debe estar compuesto por 8 dígitos más 1 guión más un dígito , quedando información como sigue xxxxxxxx-x (RUT o DNI de la persona)

Hi Carmen,

Thanks for reaching out to Jotform Support. It's easy to set up a field with a customized format. Let me show you how to do it:

1. In Form Builder, click on Add Form Element from the top left corner of the screen.
2. Go to the Basic tab from the opened window on the left, and drag/drop the Short Text field into the form.
3. Next, click on the Properties (Gear icon) option available with the Short Text field.
4. In the opened properties window, go to the Options tab.
5. Toggle the Input Mask option to ON.
6. Set the desired number of digits and hyphens you would like for the field by adding #.

Check out the screenshot below to see my results:

Muchas gracias, solucionado!
