Trying to create pop up text boxes for 'read more' 'read less' in epub mag

[sarahs81624436]

I'm developing an epub magazine and want to make half of the article appear when a 'read more' button is activated. How do i then make the button become a 'read less' and enable the article to disappear when this has been activated?

You would create two buttons (1) read more (2) read less. Then have the read less Hidden and change the buttons aroundwhen read more is clicked. Hide read more and show read less...

Best handled with a multistate object assuming this a fixed layout epub.
