Expandable/collapsable text
Hello,
Is it possible to have part of the text in iBook (using iBook Author) to be collapsed (hidden) by default so that it expands only upon readers touch? I am specifically looking for some feature like what we can see on this page http://support.apple.com/kb/HT5557 where it says "ibook features". You can click on the triangle next to it and it expands.
Thank you,
