<h5 id="GrapeCity_ActiveReports_PageReportModel_Grouping_Parent_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>This property only applies if the group has exactly one group expression</p>
<p>Indicates the following:</p>
<ol><li>Groups are sorted according to the recursive hierarchy (sort is still used to sort peer groups).</li><li>Labels (in the document map) are indented according to the recursive hierarchy.</li><li>Intra-group show/hide toggles items according to the recursive hierarchy (see ToggleItem).</li></ol>
<p>If filters on the group eliminate the parent of a group instance, it is instead treated as a child of the parent's parent.</p>
