As I understood you want to set conditions works like if a user fills checkbox, show disabled fields. Please follow these steps:
1.Create a checkbox on your form.
2. Add a Form Collapse field after the code.
Set the "Visibility" to "Hidden"
Set the "Status" to "Open"
3. Go to "Setup & Embed" and click "Conditions". Choose "Show/Hide a form field".
4. Use this condition. When the user ticks the checkbox it will immediately show the Form-Collapse field along with any field below it.
If you have any questions or issue, feel free contact us.
