You can set up table groups to collapse, so that users can drill down into the data they choose to view. In order to collapse a group, it must have a header and a nested group. When the report is initially displayed, the header rows display the groups with plus sign icons that you can click to display the detail data from the nested group.

When you view the report, the collapsible group's header rows display with a plus sign icon to the left of them. Click the icon to expand the group and show any associated details.

The drill-down feature helps in temporarily hiding a part of your report. That hidden part can be controls, groups, columns or rows. When you open a drill-down report, part of the data is hidden so that you can only see high-level data until you request for more detail. In such reports you find an expand icon (plus-sign image) next to the toggle item in the report. Clicking the toggle image, or plus sign, expands hidden content into view and the expand icon changes to a collapse icon (minus-sign). When you click the minus-sign image, it hides the content and returns the report to its previous state.

To create a drill-down report, use the Visibility properties of controls, groups, columns, or rows. Simply set the Visibility - Hidden property to True and set the toggle item to the name of another item in the report, usually a text box in the group or a text box as column label containing the hidden item. At run time, this puts a plus sign next to the toggle item which the user can click to display the hidden data.

1. From the Explorer , select the Tablix data region.
2. From the left pane of the designer, click the Group Editor icon  to display row groups and column groups.
3. Select Tablix_ColumnGroup1 column group.
4. From the Properties pane, set the Visibility - Toggle Item property to the text box containing the label Media Type (TextBox2).
5. Set the Visibility - Hidden to True.

Preview and Save Report

1. Click Preview  to view your report in the final output.
2. Click the (-) sign to expand the price details for each media type. Click (+) sign to again see the aggregate price for all media types.
3. Exit the preview mode by clicking Back on the left side of the designer.
4. Switch to the File tab and click Save to open the Save dialog box. Enter the report name and click Save Report. You can also provide a description and a revision comment for the report.  

The reports created in the ActiveReports Web Designer are saved in the ActiveReports Server Report Portal under 'No Category'.
