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.

Example

    item.actionsSections = [
      {
        title: "Show table",

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

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

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({

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

        }
      ]
    ];
   }
});

map Map|WebMap

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

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

Selected items are available in the selectedItems property.

Default Value:false

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 example, if this widget is the first of three widgets associated to the upper right hand corner of the view UI, then the other widgets will reposition when this widget is made invisible. For more information, refer to the CSS display value of "none".

Default Value:true

Example

// Hides the widget in the view
widget.visible = false;

visibleElements VisibleElements Since: ArcGIS Maps SDK for JavaScript 4.25
