I am trying to find a way to make one of the fields in my NUX form multi-line text so the user entering the information in the "details" field can easily see what they have written. I see that there is a way to create a multi-line text in a card, but I don't see any way to create a multi-line field in a NUX form.
You can add multiple line of text as a comment by a user in the NUX doing the following:
1. Add a Field card to your page
2. Edit that card and then select the "Gear" options as I highlighted below:
3. Enable multiple lines of text
EDIT: I just saw that you were referring to a "Form". In that one for the moment is not doable indeed. However, if you really need to show multiple lines, I think one workaround is to create items in a list using Field cards (Input fields) + Action (to create the items).
