Buttons need to be rectangular in InDesign. The workaround is to create multiple buttons to form the shape you need.
@Tim – the area of the button that reacts to tapping is always a rectangle.
It's independent of its visible shape. That is true for DPS.
In Flash you could use fancier shapes for that area.
For HTML I'm not so sure…
@Bob, I thought that was the case, I have done it that way before, but these are much more intricate shapes - so it's going to be a rather massive pain in the backside!
@Uwe Thanks for that side thought! I was also thinking about html5, but I don't know how to code it - best get learning haha
Thanks for the answers guys,
Much, much appreciated
