  • Upgrade Notes
  • Due to the compliexity of the size calculation (hflex and vflex) for tablechildren with colspan and rowspan, we restrict the usage of hflex and vflex for the tablechildren component to "false, min, and 0" since 7.0.2. Only the following values are supported: min, 0, and false.
  • 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.
