This topic describes the configuration items of a tab list.
Chart Style
A tab list belongs to the Interact category. It allows you to dynamically display tabs in your DataV project by using interaction events with other widgets. You can configure the color, quantity, type, and style of the tabs.
Settings Panel
- Search for Configurations: In the right-side panel of Canvas Editor, click the Settings tab, and click Search for Configurations in the upper-right corner. Enter the required configuration item in the search box, and click the search icon to quickly locate the configuration item. Fuzzy match is supported. For more information, see Search for asset configurations.
- Size: indicates the size of a widget, including its pixel width and height. You can click the icon to proportionally adjust the width and height of a widget. After you click this icon again, you can adjust the width and height as needed.
- Position: the position of a widget, which is indicated by pixel X and Y coordinates. X-coordinate indicates the pixel distance between the upper-left corner of the widget and the left border of the canvas. Y-coordinate indicates the pixel distance between the upper-left corner of the widget and the upper border of the canvas.
- Rotation Angle: the angle of a rotation that uses the center point of a widget as the rotation point. The unit is degrees (°). You can use one of the following methods to control the rotation angle of a widget:
- Directly enter the degrees in the Rotation Angle spin box or click the plus sign (+) or minus sign (-) to increase or decrease the value in the Rotation Angle spin box.
- Drag the black dot in the icon.
- Click the icon to horizontally flip a widget.
- Click the icon to vertically flip a widget.
- Opacity: the opacity of a widget. Valid values: 0 and 1. If this parameter is set to 0, the widget is hidden. If this parameter is set to 1, the widget is completely displayed. Default value: 1.
Font: the font of the tab list.
Background Color: the background color of the tab list.
Rows: the number of rows in the tab list.
Columns: the number of columns in the tab list.
Selection Type: the selection type of the tab list. Valid values: Single Selection and Multiple Selection.
Carousel: the carousel interval of the tab list. Click on the left side to enable or disable the carousel effect.
Tab Selected During Initiation: the ID of the tab to be initially selected. The value of this parameter must be the same as the value of the id parameter on the Data tab. If Selection Type is set to Single Selection, you can enter only one value. If Selection Type is set to Multiple Selection, you can enter multiple values. Separate the values with commas (,).
All Button: specifies whether to display the ALL tab. This parameter is available only when the Selection Type parameter is set to Multiple.
All Tabs Selected During Initiation: specifies whether to select all tabs by default. If you turn on the switch, the Tab Selected During Initiation parameter does not appear. This parameter is available only when the Selection Type parameter is set to Multiple.

id | The ID of a tab. The Tab Selected During Initiation parameter on the Setting tab defines the ID of the default selected tab based on this parameter. |
content | The text on a tab. |
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. |
