How do you select multiple items in a list box on a Mac?

[Igoyard]

I am new to creating PDF forms so I'm sure the answer is obvious but I have not been able to get this to work. I have selected the "Allow Multiple Selections" checkbox in the form preference and it works on my PC holding down the control button but my colleague on a Mac isn't able to make more than one selection holding down the command key. I borrowed a Mac myself to test it and tried holding control, shift, command, option, command+shift and everything else but I am not able to get it to work. Any advice?

Was the drop down list set to allow multiple selections?

If it has not, then this is not possible.

[Igoyard]

Yes they are set to allow multiple selections and it works on my PC but not on my colleagues Mac using both Acrobat or Preview.

It is the command key, and it works for me. What version of Acrobat and OSX are you using when it doesn't work?

[Igoyard]

The Mac that I have tested it on is running OS X El Capitan. I haven't been able to test it in Acrobat on the Mac I borrowed but it doesn't work in Preview and I know my colleagues couldn't get it to work in Acrobat on their Macs. I have contacted Adobe support and sent them the file and they told me they were able to make multiple selections on their PC's WITHOUT holding Control and that they were going to test it on a Mac and get back to me.

Don't expect any form to work correctly with Preview. It absolutely should not be used for forms.

I'd be interested in testing it out if you want to send it to me: acroscript at gmail dot com

I realize I am asking a year later (almost to the day!) but can you explain this answer? I have an application form at https://namati.org/network/core that is designed to work for anyone but have been able to confirm that just this issue as asked at the top does not work on OSX Preview. It is not possible to select multiple options on the pulldown, and the longer text options are truncated with ... which is also unfortunate.

So as someone who is trying to make life easy for folks who want to complete forms offline and email them in what am I to do? Should I add a note that the form should be filled in using Acrobat 5 or newer, and no other third party app? 

Thanks much for any guidance.

No it doesn't work correctly with Preview and Yes, you should somehow communicate to your users that the form should be used with Adobe Reader. Other PDF viewers may work just fine with your form, but you should do the testing yourself. As mentioned before, Preview should not be used with PDF forms at all, despite the minimal support it has.

I realize I'm very late to this thread but I'm having the same issue. I'm in Adobe Acrobat Pro DC on a Mac. I have a list box in a dialog and am unable to select multiple items even when I hold the Command key down. I'm in "Prepare Form" mode. Where is the setting for "Allow multiple selections"?

[try67]

You mentioned a dialog. Is this list-box an actual form field, or a part of dialog window? If the latter, it can't be done.

If the former, right-click it, select Properties and then look under the Options tab.

[cschmelter]

The list box is part of a dialog window so I guess I'm out of luck. I'll have to go with selecting one at a time and a "select all" checkbox where they can delete the ones they didn't want. Thanks for the quick reply.

Hold "Command".
