Interactive PDF button appearance - invisible/visible rectangle
I have several buttons in a PDF that are currently showing a visible rectangle on mouse release. I would like to change this to INVISIBLE rectangle.
1. Is there a button setting in InDesign, or something that I'm missing, that will allow me to specify this? I've set my hyperlinks to appear as invisible rectangle but can't figure out how to do this for buttons.
2. It would be ideal to set this up in inDesign, but if that's not possible, is there a setting in Acrobat that will allow me to change the appearance (of buttons - I know how to do it for links)? I found the "Appearance" tab, under button properties, in the Form workspace...but there's nothing there to edit that setting like there is for links.
When I change the event to "on click", there's no visible rectangle. But I would prefer to use 'on release'.
