How can I populate related values?

Hello, what is the best way to autofill or show related fields from another table when editing a record? I see this can be done post-transaction, but I find it more important to make it happen before the user submits the record. Thanks!

Would love to know how this was accomplished prior to form submit...

Me too, how did you do that?
