Create Rule Based Upon Unselected Dropdown Field

Create Rule Based Upon Unselected Dropdown Field

Is it possible to create a field rule that is based upon a dropdown field NOT being selected?

More specifically, I want to hide the rest of the Zoho form below this dropdown field when the user hasn’t yet selected an item from it. Basically the rest of the form shows ONLY once you make a selection in this field. Before you do this, everything below this field is hidden.

I don’t know what language to use when writing the rule to refer to the unselected dropdown field. It displays as -Select- when you view the form on a webpage but this language doesn’t work in the RULES section.

Can you help?

Thank you in advance for your support,
