[label:app_e]On the app, can I view the contents list in a tree structure by the group or the genre?
Yes, please use the "Side menu" to view the contents list in a tree structure by the group or the genre. However, the list view is available only after you select a single layer of the groups or the genres.
The entire content list cannot be displayed in a tree structure. This is to avoid overloading the system with too much information at a time for the entire display.
