TableList

AMD: require(["esri/widgets/TableList"], (TableList) => { /* code goes here */ });
ESM: import TableList from "@arcgis/core/widgets/TableList";
Class: esri/widgets/TableList
Inheritance: TableList Widget Accessor
Since: ArcGIS API for JavaScript 4.17

The TableList widget provides a way to display a list of tables associated with a Map. It is meant to be used with feature layer tables.

If a map contains feature layer tables, they will display within the widget. Tables can also be added to the map's tables collection. Any tables referenced in the map property will display in the widget. If unsure of whether the layer is a table, check the feature layer's isTable property.

The ListItem API provides access to each table, allows the developer to configure actions related to the table, and allows the developer to add content to the item related to the table.

Known Limitations The TableList widget is not supported with web scenes.

visible Boolean inherited

Indicates whether the widget is visible.

If false, the widget will no longer be rendered in the web document. This may affect the layout of other elements or widgets in the document.

For more information, refer to the CSS display value of "none".

Default Value:true
Example
// Hides the widget in the view
widget.visible = false;
