I have been preparing forms and creating text boxes, check boxes etc for some time now.
Recently, I am unsure if was a recent update or because I have updated to highSierra on my mac, there is no longer a 'no colour' option available when trying to make these boxes transparent.
I have had to move my file to a PC and do it on a previous version of Acrobat Pro.
I have deleted my plist files to see if that worked (thanks Adobe support) but still no love.
Yes I have also turned my computer on and off again.
I am also running, InDesign, Illustrator and Muse on my mac.
Anyone else come across this?
Just letting you know, still no love after the latest High Sierra (10.13.1) update as well.....
They don't want me to be transparent!
For everyone still struggling with this issue, I've developed a simple utility that allows you to set a field's fill/border color as transparent, even when this option is not available in the color selection dialog in Acrobat. It can be downloaded for FREE here: Custom-made Adobe Scripts: Acrobat -- Set Field As Transparent (FREE)
A more advanced version of this tool, which allows multiple fields selection as well as editing many other properties, can be found here: Custom-made Adobe Scripts: Acrobat -- Mass Edit Fields Properties
As many have discovered, this bug manifests in many parts of Acrobat. Someone has, very helpfully, posted a fix for all of them at the topic How to draw shape in 'Comments' with no fill
Seems the Properties Toolbar (buried in true Acrobat form) still has the abilities that have been lost in the more direct tools.
Came across this problem recently but managed to copy a transparent button from an older PDF which keeps the transparency in the DC. This PDF https://drive.google.com/open?id=185__xi4BiZmtJX_zmNmgNeZtoT27kRez has a transparent button, just copy and paste into your PDFs.
Hope this helps!
