How to create non-exclusive checkboxes with the same name in an Acrobat/PDF form
In Acrobat Professional, I create multiple checkboxes and assign the same name to each checkbox, but a different export value. With this, the checkboxes seem to behave like radio buttons: Acrobat only lets me check one of them. If the first is checked, and I click on the second one, Acrobat unchecks the first one.
If I assign different names to the checkboxes, then they do behave independently. However it would make things easier for my code that fills out the form if the name could be the same. Is it possible to create non-exclusive checkboxes (i.e. real checkboxes) that have the same name in Acrobat?
(For reference, this is the PDF I created: 20110503-exclusive-checkboxes.pdf)
Answer
Judging from the PDF Reference, it's impossible to create independent checkboxes with the same name.
In fact, a PDF Viewer should use the name to detect which checkboxes will form a check box field.
See Adobe's PDF Reference, 8.6.3 Field Types, Check Boxes (page 648) for more information.
