I have a number of PDF forms created in Adobe Acrobat that have a required drop down list.
Originally I had been adding a blank option to the top of the lists (by hitting the space bar in the Item Name and leaving the Export Value empty), so that the form displays blank when opened.
I then realized that because the "blank" option in the dropdown is not technically "null" or empty but a space that the Submit a Form button is not catching it as being empty and allows the form to be submitted.
1) Adobe: Why is there not a true "add a blank" option to the dropdown list properties that passes a "null" value so the Submit a Form button form works properly???
#1 IS POSSIBLE! Just put a space bar!!!! and press ADD~!
YOU ARE WELCOME! I WAS WONDERING ABOUT THAT SAME THING MYSELF!
That is how it is done using the UI.
I have dropdowns in my form but they default to the first value in the dropdown. I just want them to default toa blank/empty field.
That worked perfectly! Thanks for the tip!
You human legend! There you have it ladies and gents
Unfortunately, this does not solve the problem. They were using this method from the beginning, when he said, "Originally I had been adding a blank option to the top of the lists (by hitting the space bar in the Item Name and leaving the Export Value empty), so that the form displays blank when opened."
