The same field over several lines: UMG's MultiLineEditableText.
A subclass rather than a palette entry that ticks bMultiLine, unlike the boxed pair -- and the
difference is worth stating. Native.TextInput plus bMultiLine = true IS the multi-line boxed
field, and the palette offers it as a second row of the same class (see the registry). A CLASS
exists here instead because UMG has one, because .dui gains a tag that reads the way the UMG
documentation reads, and because a Blueprint that wants to subclass "the multi-line borderless
field" has something to derive from. It sets exactly one property.
