Configuration field description
Parameter | Description |
| (Optional) The contents of the first list header. |
| (Optional) The contents of the second list header. Note The |

. Other data can be customized and distributed in the corresponding rows and columns of the table in the order of the actual data content.
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. |

https://api.test
and the data transferred to the request data interface is{ id: '1'}
, the final request interface ishttps://api.test?id=1
.Import data
After data of a widget is processed in accordance with its drawing format, the widget is imported for redrawing. You do not need to request server data again.

Update component configurations
Style configurations of widgets are dynamically updated. Before this action is executed, you must click the widget in Canvas Editor, click the Settings tab in the right-side panel, and click Copy Configurations to... to obtain widget configurations. After that, change the style field for the data processing node in Blueprint Editor.
Display
Displays the widget. The following example shows the reference data.
return { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" };
Hide
The following example shows how to hide a widget.
return { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" };
Switch to the hidden state
Specifies whether to show or hide a widget. The following example shows the reference data.
return { "animationIn": { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" }, "animationOut": { "animationType": "", "animationDuration": 1000, "animationEasing": "linear" } };
Move
Move a widget to a specified location. The following example shows the reference data.
return { // The positioning type. to indicates absolute positioning, whereas by indicates relative positioning. The default value is to.
