I am developing some reports in Sitecore 6.5 using Stimulsoft report designer. I am in a need to add some filters to my reports like these ones(

I had a look at the .mrt file as well. But couldn't find any components configured for the filter. If you can provide me some information regarding this, it would be a great help.
