I have tested a bit more. The PDF will only show checked Checkboxes and Radiobuttons when it’s content has at least once a “/” between two words like “word/word” or something like “%” after a number like “50%” in it. Sounds totally random but only then content from a checked Checkbox/Radiobutton is shown in the PDF.
Thanks for your answer. I downloaded the ZIP file of your GitHub version but wordpress was not able to install it. It responds that the link is expired..
We have a Problem with Checkboxes/Radioboxes as well. The PDF grabs some Checkbox options correctly from the form and displays them in the PDF but other options it won’t show them in the PDF.
“Enable display data in the checkbox or radio buttons of your PDF file” will just show all available options (even those that are hidden in the form) but not which is marked. We also dont want to show all options since some are supposed to be hidden.
