sql - crystal reports xi show only group headings -

I have a crystal report that has an employee group grouped like this in this way:

  employee 1: -Nan-written order-ATC  

The report displays all this information but what I want to do is making a list which is only an employee and when clicked The information will be drilled down. Will there be a better way of making a drop down to select an employee?

The report is created with the parameter to obtain the amount of order from the SQL query command.

Crystal Reports Has Drilldown Functionality Maybe It Will Help
