Hi,     You can try this approach, but the compatibility is not fully tested, try   For example for UniMemo: function added(sender, container, pos, eOpts) {     sender.resizable = {         minWidth: 160,         minHeight: 120,         dynamic: true,         pinned: true,         handles: 's e se',         heightIncrement: 20,         widthIncrement: 20     }; } Best regards,
