Is your feature request related to a problem? Please describe.

Currently, the in-page nav component searches a page for h2 and h3 tags and dynamically builds the nav links based on the content of those tags. It also makes h2-based, created links bold while making h3-based links normal weight.

Describe the solution you'd like

We could offer a way to easily customize the way in-page nav searches for page headings to dynamically build the navigation block. What if a developer only wanted to use h2 tags? e.g.:

data-headings="h2"

If no data- attribute is present, the default one in the JS would be used.
