Drop-down Menu Multiple Selection on Mac with Pro 12
What is the status of enabling multiple selections in a drop-down menu by using the Shift key (using Filemaker Pro 12)?
I am working with a partner who can do this on a Windows system.
There is a forum post from July 2010 stating that this feature did not work with FMP Pro11 for the Mac:
"FileMaker does state "Note: With FileMaker Pro 11 running under Mac OS X, it is currently not possible to select more than one item from a pop-up menu."
Do we have to replace the drop-down menu with check boxes if we want to be able to make multiple selection in both Mac and Windows environments?
