Multicolumn List Box, header information is gone by drag and drop

[Tepig]

Hi, when I drag and drop a component in multicolumn list box, header information is gone....

("a" and "f" are gone...)

Does anybody know that this is a reported bug?

Is there any way not to move header but only component?

I just want to move value "1" to section "b" and "6" to section "d"... : (

I don't think this is a bug.  Drag and drop doesn't work well on its own unless it is fully implemented in code using events.  Create an event structure with a Drag Starting event on the MCLB.  The Data cluster from the event data node will show the row header of the row that is being dragged.  If you don't properly deal with this data on the drop event, it will be lost.  This is why the row headers are blank after dropping.  You, as the designer, are responsible for dealing with this information in a way that makes sense to you.
