That´s pretty simple one... part at the bottom of the page is probably multistate object and buttons have go to state action attached to them, button animation has probably been put to button´s roll over state.
When user rolls over for instance Heart Attack button, button´s roll over animation triggers. When user clicks that button, multi state object switches to Heart Attack state....
Thanks for your inputs. Yes, the buttons at both sides are quite simple as you said. I am seeking help on the Sliding animation part (you can see a red vertical line to slide). When the slider gets moved on either left or right, it shows the image on the background. Is this possible to do in Indesign? Please help. Thanks again for your help.
Oh, I didn´t noticed that, it´s not possible to make that kind of widget in InDesign, InDesign´s animation tools does not support draggable elements. Either whole SWF has been made in Flash Professional, or just the slideable image, exported as SWF and placed at the background in InDesign....
hard to tell which way....
Thank you very much for your support.
