You can display multiple list items with SharePoint and SharePoint Designer quite easy. But how do you display a single listitem? I worte a Webpart, which does this. If there are more than one listitem, you can page through them. And if you like, you can pass an itemid via a Webpart connection.
In the Webpart properties you can select the list/library. If you like, you can specify a view other than the default view.
SafeControl Entry for your web.config:
<SafeControl Assembly=“RH.DisplayListItem, Version=126.96.36.199, Culture=neutral, PublicKeyToken=7850e867f7381714” Namespace=“RH” TypeName="*" Safe=“True” />
