Your theme doesn’t appear to support it by default.

That doesn’t mean it’s not possible, just that by default your theme doesn’t seem to support it. You may want to try their support forum or their other support forum. You could also perhaps hire someone to add it for you.

Thanks Jayseae,
I tried to get an answer from the theme forum, but no response. Thanks for the link to hire someone ??
