A data system user interface that can employ different data collection renderers (e.g., views) based on an attribute of the content of a view-set (e.g., list, folder, directory) is provided. In accordance with aspects of the subject invention, views that are suitable to present certain types of content can be automatically selected. This automatic selection can employ the use of more specialized, optimized views based on the content of the view-set. The contents of the view-set can be analyzed and matched against an extensible set of view selection rules. It will be understood that, although the custom view can have a completely different visual appearance from the standard, default and/or generic view, the subject invention enables custom views to run within the same window as the standard view.
