Expandable/Collapsible Groups by Drill Through

mwilliams

Example report showing a way to have expandable/collapsible groups by using a drill through hyperlink.<br />
<br />
The report has an outer table and embedded detail table. All embedded details begin empty and hidden. If you click on a group hyperlink, the group value is added to a comma separated string parameter that is passed to the same report which shows the clicked group expanded. As you select/unselect other groups, their values are added/removed from the passed parameter to simulate the expansion and collapse of the group. Each expanded group remains expanded until the group is clicked on again to close it. The scripting for the comma separated parameter is inside the hyperlink drill through setup on the outer table group header. You can see the values being added/removed from the "expanded groups" list at the top of the report.<br />
