File upload – Displays a file selection text field and dialog box (the exact appearance differs from

browser to browser).
File uploads cannot be stored in a custom field. This user interface type requires special form
implementation support and is not recommended for use in custom fields.
Hidden field – If Hidden Field is selected in the User Interface drop-down list, the field is not displayed

to the user, but is submitted with the form. This option is often used to force a specific value such as a
user's role or an expiration date. However, it is possible for someone to use browser tools to modify the
intial value when the form is submitted. If the value should be forced, use the Force Value setting under
Advanced Properties to ensure the value cannot be overridden. For more information, see
Form Field
To set the value to submit for this field, use the Initial Value option in the form field editor.
