class Item in Zircon Profile 8.0

Provides a display-only form element with an optional title and description.

Note: since this is a read-only field, setting the #required property will do nothing except theme the form element to look as if it were actually required (i.e. by placing a red star next to the #title).

Plugin annotation

@FormElement("item");
