We're tried using the contact web part with a Group By to collapse
the contact list. This works fine except that the Group By criteria
is included in the header (ie: Department: Finance). Our users want
to get rid of the "Department:" piece and just show the field value.
Since we couldn't figure that out, we are using the Data View (XSL)
to present the contact list. This works, except now the people
listed aren't clickable (to see details) even though we've selected
the Last Name with link field.
