Answer 1

I think you're saying that you need the user to enter listable items in a textarea and need to support the ability to present a single option across multiple lines.

As you've seen, using a single newline as the item separator does not work - you can't differentiate between two items on one line each and a single item presented on two lines.

Use two newlines instead of one as the item separator.

Example input:

Item One

Item Two line 1
Item Two line 2

Item Three

Answer 2

You can use whatever separator you like. For example an empty line (as when separating chapters), or a comma or semicolon. Any character (or sequence of characters) that is not part of the text to be entered.

Just remember to tell the user what to use as a separator.
