What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Let me please inform you, that most of the widgets are not the JotForm native fields. It means that conditional logic is not optimized on them.
I have attached a feature request about the conditional logic improvements for mentioned Dual ListBox widget. If you would like to use conditionts with some other widget, please open a new thread and provide us with the full widget name. In this case we will be able to escalate an additional request to our Development Team.
We will get back to you via this thread once we have any updates.
