    Really long scroll lists are usually a problem for a GUI.

    Is there a Unity suggested method for handling this type of list in the new uGUI?

    Have you tried just extending the size of target scroll object to fit the contents? It is quite possible that Unity's systems will manage this appropriately, as-is.

    If it's really long, you may want to create the objects as-needed via object pooling. You don't want to create 3000 GameObjects to represent your 1000 objects when you are only seeing 10 of them at any one time.

    Yup true, I was considering a backing class to handle the display of only a few at one time. DFG had a nice implementation for this. I was wondering if Unity have a suggested method and if so a tutorial would be good, since mobile performance is a key topic.

    Not yet, I don't think.

    Any news on this one? Currently i'm trying to have a masked list of 20 items. Each item has few states in different game objects (controlled using setactive true/false) and with 20 items i get roughly 30fps in editor. The only solution i found so far is to hide all the objects that are outside of the mask.
