TableList

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.

For information about gaining full control of widget styles, see the Styling topic.

Example:

const tableList = new TableList({
  map: map, // takes any tables associated with the map and displays in widget
  selectionEnabled: true,
  listItemCreatedFunction: function(event) {
    let item = event.item;
    item.actionsSections = [
      {
        title: "Show table",
        className: "esri-icon-table",
        id: "table",
        type: "toggle"
      },
      {
       title: "Layer information",
       className: "esri-icon-description",
       id: "information"
      }
    ]
});

Property Details

container String|HTMLElement inherited

The ID or node representing the DOM element containing the widget. This property can only be set once. The following examples are all valid use cases when working with widgets.

Examples:

// Create the HTML div element programmatically at runtime and set to the widget's container
const basemapGallery = new BasemapGallery({
  view: view,
  container: document.createElement("div")
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// Specify an already-defined HTML div element in the widget's container

const basemapGallery = new BasemapGallery({
  view: view,
  container: basemapGalleryDiv
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

// HTML markup
<body>
  <div id="viewDiv"></div>
  <div id="basemapGalleryDiv"></div>
</body>

// Specify the widget while adding to the view's UI
const basemapGallery = new BasemapGallery({
  view: view
});

// Add the widget to the top-right corner of the view
view.ui.add(basemapGallery, {
  position: "top-right"
});

declaredClass Stringreadonly inherited

The name of the class. The declared class name is formatted as esri.folder.className.

iconClass Stringinner

The widget's default CSS icon class.

id String inherited

The unique ID assigned to the widget when the widget is created. If not set by the developer, it will default to the container ID, or if that is not present then it will be automatically generated.

label String

The widget's default label.

listItemCreatedFunction ListItemCreatedHandler

Specifies a function that accesses each ListItem. Each list item can be modified according to its modifiable properties. Actions can be added to list items using the actionsSections property of the ListItem.

Example:

const tableList = new TableList({
  map: map,
  selectionEnabled: true,
  listItemCreatedFunction: function(event) {
    let item = event.item;
    item.actionsSections = [
      [
        {
          title: "Go to full extent",
          className: "esri-icon-zoom-out-fixed",

        }
      ]
    ];
   }
});

map Map|WebMap

A reference to a map containing the tables. Set this property to access the underlying tables within the map.

Example:

Layer.fromPortalItem({
  // Loads a layer (table) from a portal item
  portalItem: { // autocasts new PortalItem()
    id: "add portal item id"
  }
}).then(function(layer) {
  // Load the layer
  layer.load().then(function() {
    // Check if the layer is a table
    if (layer.isTable) {
      map.tables.add(layer);
      console.log(map.tables);
    }
  });
});

const tableList = new TableList({
  map: map //  map contains tables collection
});

multipleSelectionEnabled Boolean

Indicates whether more than one list item can be selected by a user at a single time. SelectionEnabled must be set to true for this property to have an effect on the widget.

Selected items are available in the selectedItems property.

Default Value:false
