Yes, you can do this in QML, coupled with some Javascript and signal handlers. But why on earth would you want to, when it's so much easier to have it in the model? If you want to, you can add a bool flag on each item that says if it's your special item or not. Let it sit in the model, it's *by far* the easiest for you. If you are worried about tainting your model with something that doesn't match the concept it models, then you're on the wrong track. Your UI obviously mixes concepts in the same area, which is why you have a problem with the low-end model code. Fix your UI to not show a special item that is a different concept, or accept that you should add it to the model. I would choose one of those two options, because the others are worse.
