Add subsessions for agenda shortcode
It is a common request to have sub sessions. We have been displaying sub-sessions in abstracts or as their own sessions titled as main session: sub-session name
.
The long term solution should be to just add an indent level field in agenda.yml. This way we can visually emphasize that the session is a sub-session without breaking out of the table format, or having verbose and repetitive titles.
items:
- name: Some session
- name: Some sub-session
level: 2
- name: Some other session
