There is no simple way to do this.

You could try
- hooking the OnEnter script of the dropdownmenu buttons
- check that the parent of the button is "your" dropdown
- and do a GameTooltip:SetHyperlink(itemlink)

I haven't done this anywhere and I don't think it's worth the trouble tbh.

Yes... no :p

He's not asking how to have the tooltip show without having Beginner Tooltips enabled.
There's a new flag info.tooltipOnButton which you can use to show tooltips regardless, so Xinhuan's workaround is no longer needed (and additionally won't even work because in 4.3 GameTooltip_AddNewbieTip is not called if the flag is set)

OP's sample code already uses that flag.

Adding the OnEnter handler from 4.3 for reference

            <OnEnter>
                if ( self.hasArrow ) then
                    local level =  self:GetParent():GetID() + 1;
                    local listFrame = _G["DropDownList"..level];
                    if ( not listFrame or not listFrame:IsShown() or select(2, listFrame:GetPoint()) ~= self ) then
                        ToggleDropDownMenu(self:GetParent():GetID() + 1, self.value, nil, nil, nil, nil, self.menuList, self);
                    end
                else
                    CloseDropDownMenus(self:GetParent():GetID() + 1);
                end
                _G[self:GetName().."Highlight"]:Show();
                UIDropDownMenu_StopCounting(self:GetParent());
                if ( self.tooltipTitle ) then
                    if ( self.tooltipOnButton ) then
                        GameTooltip:SetOwner(self, "ANCHOR_RIGHT");
                        GameTooltip:AddLine(self.tooltipTitle, 1.0, 1.0, 1.0);
                        GameTooltip:AddLine(self.tooltipText);
                        GameTooltip:Show();
                    else
                        GameTooltip_AddNewbieTip(self, self.tooltipTitle, 1.0, 1.0, 1.0, self.tooltipText, 1);
                    end
                end
            </OnEnter>

Ah! well i stand corrected..

but from the looks of it the hook could be modified instead to use the GameTooltip's OnShow script instead of the hook to GameTooltip_AddNewbieTip
