How to style each line of a textarea list?

[ZiNgA BuRgA]

Option 1:
Allow multiple values for the field, set delimiter to be  .
If all are the same format, use in Display Item Format

Code:

<span class="item">{VALUE}</span>

---

otherwise use the Format Map List to assign specific mappings.

Option 2:
If you wish to keep it to be a singular value, use the following as the Display Format

Code:

1 2 3 4 5 6 7

<span class="item"> <?=str_replace("\n", '</span><span class="item">', str_replace("\n\n", "\n", str_replace("\r",'',trim({VALUE})) ) )?> </span>

---

May be an issue if the user decides to put multiple blank lines.
(this also assumes that the Display Parsing is set to Plaintext (without newlines))
