Our teachers need to enter 1 or more form fields with a list of text it

Our teachers need to enter 1 or more form fields with a list of text items. The sub menu reminds them to enter a comma after each item, followed by 1 space.

Is there a way that a condition can be set up so that if a teacher forgets to enter the commas/spaces, that their entry will be rejected until they do?

Hello,

Unfortunately there is no option to set a condition to require a user to input a comma for it to validate the input. Is it possible instead to separate each item with a separate textbox? If so, you can instead make use of an infinite list widget, or a configurable list widget to be added into your form.

If this solution does not fit your requirements or if I'm misunderstanding them, it would be great if you can provide more details on this matter, we'd love to hear them.
