HEAD
- Inline role switcher now includes sections.
- Two cases:
(a) User is a CC
- For any roles with active sections, javascript pop-up requires section (or blank for no section) to be entered.
(b) User is not a CCa
- Sections are accumulated (including "No section" case) for each active role/section current user has.
- If user has roles for more than 1 section for a particular role, javascript popup requires section (or blank if user has "no section" for the role) to be entered.
- If user has only one section, new role defaults to that section.
