How to view the hidden fields in the form designer?

Does that workaround only enabled in certain browsers? I'm using Firefox, and clicking Line Layouts still doesn't show the hidden fields.

I have checked a form with hidden fields in the Advanced designer and the hidden fields are now displayed normally. It seems that it is no longer needed to disable the conditions or the other workaround to change the line layout. If you are still experiencing the issue, please let us know the form ID/URL so that we can take a look and provide you with necessary assistance. 

Thank you! 

The form I'm working on currently is here, but I have never been able to see hidden fields in the form designer on any of the forms I've made since I started using jotform.

I have cloned your JotForm and see that some of the fields are set to hide from the field properties along with the conditionally. Since the fields are already hidden by the conditions, it is not required to set the fields to hide manually. The fields set to hide manually cannot be displayed in the form designer. Please disable the option to hide the fields from the Advanced tab of the field properties so that they should be displaying correctly in the Form Designer.

Thanks!

Okay, I thought fields had to be hidden before the conditions would work. I don't know where I got that idea, but at least this was an easy fix. Thanks!

No problem. If you need any further assistance, please let us know here. We will be happy to help.
