Constructing a dynamic PDF
I want to include the solution of a math problem under its statement, but not in full view. I would rather have a page segment that can be brought to view by activating a button and made hidden when not needed. One solution is to use tooltips. However this option covers portions of the page and appears as a different format. I would rather have a page segment that drops down and appears as mostly like the continuation of top portion of the original page. This is to be in the context of a basic PDFLaTeX output for viewing on a monitor (not for presentation). What would you suggest?
