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"
});

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.

  selectionEnabled: true,
  listItemCreatedFunction: function(event) {
    let item = event.item;

  // 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

See also:

selectionEnabled
selectedItems

Example:

tableList.selectionEnabled = true;
tableList.multipleSelectionEnabled = true;

selectedItems Collection<ListItem>

A collection of selected ListItems representing table list items selected by the user.

See also:

selectionEnabled

selectionEnabled Boolean

Selected items are available in the selectedItems property.

Default Value:false

See also:

selectedItems

Example:

tableList.selectionEnabled = true;

tableItems Collection<ListItem>readonly

The collection of table ListItems displayed within the widget.

viewModel TableListViewModelautocast

The view model for this widget. This is a class that contains all the logic (properties and methods) that controls this widget's behavior. See the TableListViewModel class to access all properties and methods on the widget.

}, function(error){
  // This function will execute if the promise is rejected due to an error
