HiddenField

A hidden input element for passing values that should not be visible or editable by the user, such as identifiers, tokens, or tracking data. Unlike other field components, HiddenField does not inherit from FieldBase and has no label, validation display, or accessibility markup.

Basic Usage

<ArcadiaForm Model="model">
    <HiddenField Name="UserId" Value="@model.UserId" />
</ArcadiaForm>

Parameters

Parameter	Type	Default	Description
`Name`	`string?`	`null`	The form field name submitted with the hidden input.
`Value`	`string?`	`null`	The hidden value submitted with the form.
`AdditionalAttributes`	`IReadOnlyDictionary<string, object>?`	`null`	Any additional HTML attributes to apply to the hidden input.

Notes

HiddenField does not inherit from FieldBase. It renders only a <input type="hidden"> element.
No label, helper text, or validation errors are rendered.
Use this for form values that must be submitted but should not be shown to the user.

Accessibility

Hidden inputs are not visible and not focusable, so no ARIA attributes are needed.
