    Can a Line be required based on another line's answer?

    Asked by JalaClothing on October 04, 2013 at 01:25 AM


    We have created a wholesale application form. If the person filling it out is in the state of CA they are required to submit a California Sellers Tax ID#. But if they are in another state its note required. We want this line to be required if they select CA for the business address. How do we do this?

    Hello JalaClothing,

    That's very much possible to achieve. You can make the "Tax ID#" field as required and add conditions to show/hide this field based on the state selections.

    If someone selected CA from the state, it will show the "Tax ID#" field. As this field is already set as required, it will become mandatory for users to fill in.

    Here is a small demo form I created for you:  http://form.jotform.co/form/32754675364867

    Here are the steps to achieve this:

    1. Add a dropdown to list states.

    2. Add a textbox in your form and mark it required.

    3. Add condition to show hide the textbox if the value of dropdown selection matches:

    Here is a guide which should help you understand how show hide condition works:  https://www.jotform.com/help/57-Smart-Forms-Using-Conditional-Logic

    Hope this helps.

    Thank you!
