It can't be done in PDF. PDF interactivity has a lot of limitations, and isn't even implemented in all PDF readers.
The closest in PDF is to click a button which makes another button visible. This is called Show/Hide buttons:
Thanks for the reply. Is there some other way to do it in InDesign without resorting to the final product being presented in a PDF?
InDesign has several other different kinds of output:
* EPUB Reflowable
* EPUB Fixed Layout
* Publish Online (requires CC 2015)
* Digital Publishing Solutions
* SWF (outdated)
You would need to investigate the advantages and disadvantages of each. It all depends on what you're trying to create, what your audience is, how much time you want to put into learning a new technology, and how much money you want to spend.
I appreciate it.
