Display detailed counts
There is a link on the event dashboard which will display detailed counts of registration types, additional items and custom questions, if the custom question has a value that can be enumerated.
For example - a display of registration types:
A display of Additional Items:
And a display of custom questions:
Note that some custom questions just show you the number of entries since there is no enumeration.
The link under the display allows you to refresh the counts as you look at them.
