Create in-page section menu based on heading levels

[billymeinke]

For the strategy posts, there are more sections than can be easily scrolled through. It'd be better to have an in-page menu to jump down the page to sections based on their h2, h3, h4 etc heading levels.

@fjumawan will add some examples.

What do you think, @enriquezm?

@enriquezm Here are some examples that incorporate such features such as contents and sections: https://www.jisc.ac.uk/guides/make-your-collection-available-for-learning-and-teaching

Note: This would only need to appear on the Strategy page template for now, as there may be unnecessary headings assigned inside a how-to tutorial.

@billymeinke @fjumawan created a table of contents for strategies. Still need to work on dynamically moving it around based on page position.

Awesome, thanks for this @parkjc.

@enriquezm Would you be able to take look at this and help the sidebar items (or just the submenu) float down as users scroll? Thanks!

[enriquezm]

@billymeinke for sure! I'll look into it.
