- and for the most complex dropdown buttons like ForeColor, BackColor, InsertTable, which have unique and complex design for their dropdowns, RadEditor use Ribbonbar templates. These template buttons cannot be modified and for this reason currently they cannot be rendered as the split buttons. The tools displayed in the templates are rendered in the ribbonbar as in the Default standard toolbar of RadEditor, without modifications.
