Data item hierarchy

The data item hierarchy displays the hierarchy of available data items for the filter type associated with the currently open filter.

It provides the mechanism of restricting the data items displayed into manageable subsets. These subsets can be viewed by expanding and collapsing the hierarchy tree. Clicking on a node in the data item hierarchy displays the available data items it contains, in the data item list.

The default position of the data item hierarchy is the top left of the Filter Designer dialog.
