Select element (drop-down list)
A selection field is a drop-down list with predefined values from which your visitors can (or must, if the field is a mandatory field) select a value.
The placeholder is not a selected or selectable value.
The type of this field is always Text. A list of values available for selection can be displayed via the Values in the Field properties where each line corresponds to a value.
In addition to the selection element, there are two predefined selection elements for the salutation and for selecting a country.
