In the Document window, a thin, tabbed, gray outline appears around the repeated region. (Youll need to deselect the table to see it.) Later, when you preview your work in a browser, the gray outline will disappear and the selection will expand to display the specified repeating elements in the XML file.
Dreamweaver also shortens the length of the XML data placeholder. This is because Dreamweaver updates the XPath for the XML data placeholder so that it is relative to the path of the repeating element. For more information on this topic, see About XML data and repeating elements in Using Dreamweaver.
