Arena Chess GUI - How to display multiple engine variations?

I've been looking for any free chess GUI at all and finally found Arena. I used to use Chessbase Light a long time ago. One thing I'd really like to find out how to do is to see the Engine's top three (or top X) moves during its infinite analysis, instead of only its top move. Is there any setting I can change for it to display this? And if not is there a different GUI that does have this option? Thanks!

The engine must support multi-PV, but assuming it does, just go into the Arena menu "Engines --> Engine 1 (or Engine 2, etc) --> Configure".

There will be a MultiPV option that can be changed.

Thank you for this thread 5 years later, really helped me.
