The Hidden element lets you include a value with the form submission without displaying a field to the user. Use it to record information such as the source of an inquiry or a campaign identifier.
Adding a hidden field
Add a Hidden element to the form, then open its settings.
Set the Label to identify the information you want to record, such as Inquiry source. On the Data tab, set the Default value to the value you want to submit, such as Contact page.
The field is not displayed on the website. Submit a test entry to check that its value appears in the notification email and saved entry.
Settings
Basic
Label
Sets the label used to identify the element in the form builder, notification emails, and saved entries.
Styles
Custom CSS class
Add a custom CSS class to the hidden input, or multiple classes separated by a space. This can be useful for selecting the field with JavaScript.
Data
Default value
Sets the value of the field when the form is first displayed. You can insert a variable by clicking the code icon beside the setting.
Dynamic default value
Allows the field value to be populated from a URL parameter, block value, shortcode attribute, or filter hook. See the Dynamic default value guide for more information.
Parameter name
Sets the parameter name used as the source of the dynamic default value.
Show in email
If enabled, the submitted value is included in the default notification email. This setting is enabled by default.
Save to database

Advanced
Unique ID
The unique element identifier is displayed here. You may need this for advanced usage.
Visibility
Choose Everyone, Logged in users only, Logged out users only, or Admin only to control the element’s availability. The field remains hidden on the website regardless of this setting.
Hidden field values
Hidden values are included in the page’s HTML and can be changed by users through browser tools. Use them for supplementary information rather than confidential data or values that must be trusted.
