The typical hint menu system will be structured into a top-level hint menu that contains a set of sub-menus for the main areas of the game; each sub-menu will have a series of Goal items, each Goal providing a set of answers to a particular question. Something like this:

topHintMenu: TopHintMenu 'Hints';
+ HintMenu 'General Questions';
++ Goal 'What am I supposed to be doing?' [answer, answer, answer];
++ Goal 'Amusing things to try' [thing, thing, thing];
+ HintMenu 'First Area';
++ Goal 'How do I get past the shark?' [answer, answer, answer];
++ Goal 'How do I open the fish tank?' [answer, answer, answer];
+ HintMenu 'Second Area';
++ Goal 'Where is the gold key?' [answer, answer, answer];
++ Goal 'How do I unlock the gold door?' [answer, answer, answer];

Note that there's no requirement that the hint menu tree takes exactly this shape. A very small game could dispense with the submenus and simply put all of the goals directly in the top hint menu. A very large game with lots of goals could add more levels of sub-menus to make it easier to navigate the large number of topics.
