Is it possible to create a field with conditions?

One field will ask: Would you like to hear from us?

- If yes, a second field should pop up asking for an email address.

- If no, the email field should not be shown.

Is this a possible setting in jotform?

Thanks for you help!

Yes, you can achieve that by using Conditional Logic.

You can't actually create a field, but we can use a Condition to Show/hide a form field when the Would you like to hear from us is checked.

Here is a demo form, which you can clone to take a look at how it was made.

Please let us know if you need further help and we will be happy to assist you.
