Table 1. Parameters

Parameter	Description
Controlled Mode	If you turn on the switch, data is not requested when a widget is initialized. Data requests are triggered only based on callback IDs or the method configured in Blueprint Editor. If you turn off the switch, data requests are automatically triggered. By default, the switch is turned off.
Auto Data Request	After you select the Auto Data Request check box, you can enable dynamic polling, and manually specify the polling interval. If you do not select this check box, data is not automatically requested. You must manually refresh the page to request data or use Blueprint Editor or callback ID events to trigger data requests.
Data Source	In the right-side panel of Canvas Editor, click the Data tab. Click Set next to Static Data. In the Configure Datasource panel, select a data source from the Data Source Type drop-down list. Enter code for data query in the code editor, click Preview Data Response to preview the response of the data source, and then view the response. For more information, see Configure asset data.
Data Filter	If you select the Data Filter check box, you can convert the data structure, filter data, and perform simple calculations. If you click the plus sign (+) next to Add Filter, you can configure the script for the data filter in the editor that appears. For more information, see Use the data filter.
Data Response Result	The response to a data request. If the data source changes, you can click the icon next to Data Response Result to view the data response in real time.

Interaction

Select Enable to activate the interaction feature. When a tab is clicked, a data request is triggered, a callback value is returned, and the tab content is dynamically loaded. By default, the id and content values from the data are returned. For more information, see Configure a callback ID for a widget.

Blueprint Editor interaction configuration

1. In Canvas Editor, right-click a widget in the Layer panel and select Add to Blueprint Editor.
2. Click the icon in the upper-left corner of the page.
