Usage Example

In some cases you may want to view the data in more than one way. Whenever you want to do this, specify one or more drill-to portlets.

For example, suppose you have a portlet that shows a collection of requests. However, you would like to be able to view the breakdown of requests sorted by priority and have insight into some of the requests' details. To provide this information, you would create two drill-to portlets, one showing the requests sorted by priority and the other showing the selected details of the requests. Then you would configure your portlet such that it is linked to these drilldown pages (drill-to portlets).

When you click key areas within the portlet having the drilldown pages, the appropriate data from the drill-to portlets is displayed.

The following figure shows an example of this kind of scenario.

Figure 3-1. Portlet having drilldown pages

If you click either the skyblue (6%) wedge or the Urgent link, the drill-to pages having requests with urgent priorities are shown (see Figure 3-2. Drill-to portlets showing urgent priority requests). Note that the drill-to page on the left shows the list of requests having the selected priority, whereas the drill-to page on the right shows the selected details of the request.

Alternatively, if you click either the yellowgreen (9%) wedge or the Low link, the drill-to pages having requests with low priorities appear (see Figure 3-3. Drill-to portlets showing low priority requests).
