Forms - choose more than one from a drop down list

[fenelonk]

I am creating a form in Acrobat 7 ive used forms before.
However in this form I want to have a list of about 100 items but I want them in a scroll list so they don't take up pages and pages of space, but I want the client be able to choose more than 1 from the list. I know normally to choose more than one you would use check boxes but I want the list scrollable to save space?

Does anyone know if you create lists in acrobat 7 that can be scrollable but that you can choose more than one from the list?

any help would be much appreciated
