I'm trying to make an interactive PDF document in InDesign CC 2018.
I need the document to include dozens of buttons that change from an outlined circle to a filled-in circle, and stay filled-in, when the user clicks and releases them.
Check boxes could do this. But InDesign adds tick marks to checkboxes. I don't want this: I need a circle outline or a filled-in circle.
I know this could be done using Acrobat Pro, but due to number of the check boxes and how they have to be positioned, I'd prefer to do this in InDesign.
