SSRS - Conditional Parameters

Is it possible to have parameters in an SSRS report be hinged off of one other? For example, one of the most prominent AJAX examples is the three dropdown boxes where you select an item from the first dropdown and the second is filtered out with results that only apply to the value selected in the first one. Then you select an item in the second and the third one is filtered out with results that only match the criteria selected in dropdown #2. I am wanting to accomplish this type of scenario with SSRS.
