  • Due to the better user-firendly for the scrollbar layout, we changed the org.zkoss.zul.nativebar of the library property to true by default for Grid, Listbox, Tree and Borderlayout component.
  • Change the default value of data-embedscrollbar from false to true, if the org.zkoss.zul.nativebar setting to false.
