The Lesson appears as follows.
If a Lesson section is selected, there are a few variations on what could occur.
1. If the section has subsection information within, a tree view expands beneath it.
The current page a user is on highlights. Note: a user can click on a specific page to access it through the Table of Contents or use the Next and Back buttons on the screen.
If the main chapter page is clicked on again, the tree view with the pages re-closes.
2. The sections could have no subsections within in it. In that case, nothing would expand beneath it, but the content assigned to that section would appear and play.
