scrollbox Multiple selection

Not good news with the FDK dialogs. The description of the ScrollBox reads:

F_ApiScrollBox() displays an array of items and allows the user to choose one.

The arguments for F_ApiScrollBox() also define 'selected_item' as IntT. So unless anyone knows of an undocumented feature, the answer is single selections only.

The reason I asked if you are using ExtendScript is that you can allow multiple selections in its equivalent control.

One way to get around this limitation is to use the double scroll box concept to move items between the two scroll boxes which can be seen in several places in the FrameMaker UI:

I hope that this is useful information?
