Where did you see it can store map values? Text is text so I suppose you could save longitude or latitude but anything more complex I’m not sure how it would do that. I guess you could save it all as a rext string and parse it out later but I don’t know of any higher level organization to the input_text other than passwords.
The input_text creates a single string, you can determine the length. That’s about it. Oh the map is referring to the fact the the item created must be identified as an input_text. It’s not a map function or anything else.
