Building links
Gadgets can link to data selection gadgets, either automatically or by user configuration. Automatic linking helps users build dashboards quickly. Developers assign manual links to interact with different data objects, to add scripts to gadget event communication, and to disable selected links on a dashboard.
The following gadgets can filter data by linking to data selection gadgets:
Designers can choose to link gadgets to any data selection gadget. For example, when a list gadget showing city choices is linked to a list gadget showing country choice, only cities in the selected country are displayed.
Other gadgets such as import gadgets or HTML gadgets can also link to data selection gadgets, such as a list gadget. The dashboard designer must add JavaScript to these gadgets to receive and process values and events that they receive.
For example, an HTML gadget can link to a list gadget. The dashboard designer adds JavaScript to the link of the HTML gadget that is executed when the user selects a value in the list gadget.
