how can i make “optional required fields”? So the user has to fill at least one of multiple fields, but she can choose freely (or she can fill all of them).
awesome support! 🙂 The custom code did the trick.
Just a quick question. I use a child theme, and which is the better approach to add these custom codes: put them into the child theme’s functions.php or create the new plugin quform-custom-code.php? Or is there no difference between them?
