Dynamic Dropdown widget: the option to make sub-dropdowns as required

With a nested drop down (Dynamic Dropdowns Widget) can I make the Child responses required? I have the field set as "Required" but it only requires that the first (Parent) drop down be answered, but I have multiple dropdowns in the same one field that I would like to be required before the form could be submitted.

It's not yet possible as far as I could see in the configuration. Let me forward this thread to our backend team. If there are updates, you should know it through this thread.

If you want a workaround, you can use the regular dropdown then configure them to show/hide through conditional logic. However, this means that you'll have to add each sub dropdowns. Here's a test form for this method: https://form.jotform.com/63027242284956.
