The intent is for the solution to be hidden by default, and only shown
after an explicit action by the reader.
The explicit action can be:
- Clicking a dumb link, which takes the reader to a special page that shows
only the solution
- Clicking a button, which shows the solution using Javascript
To set up the special page, this filter needs special setup in the view.
So, it can only be used within lesson pages.
