Thanks for your suggestion. That is the method I have been using but it would be much better if the process was dynamic and the listings just disappeared from the group.
This is not an ideal solution, but that’s the one we chose to stick with for now. If we were to update the right hand content view automatically, all sorts of things could happen, e.g. you could change a listings title so it is not included in the smart group anymore.
Getting this right takes some time, we didn’t want to invest at the moment, given all the other stuff on our to do list.
