+The white area contains all the columns that were not checked as "VG" in the report designer. Here, the columns were the count of the orders for that visual group, how many total units are on the order, and the unit price of each item. You can modify the behavior of the VG aggregate functions on the [[Advanced box|http://wiki.izenda.us/Guides/ReportDesign/4.0-fields-tab#4.8-Advanced-Field-Settings-Button]] of the fields tab by changing the **subtotal function**.

+The VG hierarchy style will create a flat hierarchical representation of the data using the visual group fields as containers. But instead of displaying each level of the hierarchy below the container field's value, it displays it to the right. It also displays all levels expanded by default instead of collapsed by default. You can expand or collapse containers like with the analysis grid.

+If you attempt to expand a level without also expanding the one before it, nothing will happen. But if you then click the level before it, then all the data within the child level will be expanded as well. If you click the parent level first, then all the child levels will retain the expanded/collapsed state they had when you closed the parent level. Below is an example of the VG hierarchy.
