Thread: Indenting catergories

Indenting catergories

Is it possible to get the third level of catergories to indent?

For example if you had

Vehicles

Cars
Types of cars
Motorbikes
Types of motorbikes
Boats
Types of boats


Is it possible to get this third level of categories to indent as above or even better can you hide the third level until the second level has been clicked on? Hope this makes sense.

Thanks
