Multi-column menu

I am using Xtreme ToolkitPro 2006 Q2 (version 10.2).  Is that possible to create a multi-column menu?

I am trying different ways but failed.

One way I did is to add a function in CXTPMenuBar. which can be create a CXTPMenuBar from a HMENU object. (or CMenu).
(I create my CMenu object in another way. you can suppose it's created from
LoadMenu API which is a typical windows API to create menu object. ).

I have add MFT_MENUBARBREAK|MFT_MENUBREAK flag which can cause a column break according to MSDN when I add menu items to the menu object.  but it seems XTP doesn't translated this flags... The menubar I created still is a one-column menu.

And I also tried with CXTPCommandBars::TrackPopupMenu function , and it doesn't work too.

When I add lots of menu items in the menubar, there will be an up arrow at the top of the menubar or a down arrow at the bottom of the menubar.
(not true with CXTPCommandBars::TrackPopupMenu).

I searched the forum, And I find some body talks about xtpFlagWrapRow 
flag. But I searched all the source codes of XTP, and can't find where this flag is defined ? Am I using a different version ?

Thank you:), One more question, Since which version the feature of multi-column has been added ?
