Hello flow7,
sorry for my late reply, I must have missed an email, pointing me to your post here.
At first I thought it should be possible right from scratch and you could just add a simple shortcode like [cmm_active_group category=’1′].
But… no it doesnt’t work.
After testing driving this for some minutes now, I what’s the reason for this missing feature and I think adding it, will be no big deal.
I’ll have a look and give you feedback over here.
