Wrap

You're probably looking for automatic word wrapping? In this case the Wrap enum is not the correct one - it's used for the style.flex property (see Unitys documentation for IStyle). You can find more information about the related CSS property here: https://developer.mozilla.org/…lex-wrap?retiredLocale=de

If you want to handle automatic word wrapping, you have to set the whiteSpace property (Unity doc) instead

//Enable automatic word wrapping
label.style.whiteSpace.set(WhiteSpace.Normal);

Of course you can also write \n into your text to force a line break at that position
