Hidden Field

A value that travels with the record but is never shown in the form. Takes the same settings as Text — they simply have nothing to affect.

For a constant the template needs and the editor should not touch: a layout marker, a counter, a technical key.

Output is the same as any text value:

<section data-variant="{$variant}">

Hidden is not protected

The value is in the page source and in the form that gets submitted. It hides the field from the editor's eyes, not from anyone who looks. Nothing that matters for security belongs here.
