I'm still on MC30. I was wondering if there's more line's now for genre in the tagging list.
Genre is still a single line for some reason.
Yes, only a single line, which I find acceptable, but unfortunately it is buggy:
In the Tree, Genre only displays a single entry (followed by ellipsis), even when a semicolon delimited list is entered into the field's text box, as can be seen in my first two attachments. This certainly is a bug, especially since the whole list is displayed in a Panes view and other Content Panel lists. It is somewhat mitigated if you hover the mouse over the tree entry, in which case a popup lists all entries.
A work-around is to define a custom field, [Genres] for example, (third attachment) which uses an expression to display the [Genre] entries as a list in the Tree. Works OK in one direction, but things get out of sync if you change entries in [Genres].
As shown, [Style] does not have the same display issue (though I defined a list [Styles] anyway). As expected, the line is filled as much as possible, and the ellipsis only appears when the Tree is too narrow to display the whole list on one line.
