I created utility styles for .section-header that sticky the header as you scroll through a list.
Example: https://www.andrewsclasses.com/courses
How can I make this display easier to configure?
Can be done with specific groupings, formatting, and options. Views Template?
Keep as utility style to use elsewhere, with views style to encapsulate?
Add to Mantra Views module.
TODO: Document how to theme views groupings.
