Validate a form field based on user typing

Searching the forum I couldn’t find an answer to my question so apologies if I missed it but Is there a way to validate a form field based on user typing?

I am trying to make a learning module that helps team members memorize product highlights and features by reading, then submitting from memory to see if they know it.

Can you explain more about validating here? Do you mean you want to see if they type the highlights and features correctly?

I’ve moved on from this question as it wasn’t going to solve some other things I need as well. Apologies for the forum clutter. But will leave for anyone else struggling with this and they can tag on.
