Jaspersoft: Dropdownlist in iReport

I am trying to create a parameter which should be a dropdownlist. I need to let the use choose from 3 different values.

Is this possible? Or will I have to code one myself in Java? If so, how can this be done?

I'm usi开发者_JAVA百科ng iReport Designer 4.0.2.

Thanks!
