You can view, edit, or create list or library items in Cross Site Display just as you can in the source list or library. The appropriate display, edit, or create form is displayed, and includes the same options provided when performing these actions in the source list or library. When you exit the view, edit, or create form, you will be returned to the page containing the web part (not the source list page).
In this example, we are showing the view called Active Tasks. You may opt to look at a different view.
A user who wants to create a new task using Cross Site Display simply clicks the New button in the web part. The task is created in the source list and content is displayed depending on the filtered view.
