trigger event from single checkbox

How to use a single checkbox to control the visibility of another field in CF.

Overview

The issue arises because the standard checkbox configuration does not automatically trigger visibility changes for other form fields.
Use the CF event trigger with "Value is Empty" for unchecked and "Value is Not Empty" for checked states, then apply a show/hide listener to the target field.

Hi kraadde

Glad you found the solution, what was the solution you found for other users ?

The "Value is Empty" and "Value is Not Empty" triggers can be used for "not checked" and "checked"
