Layer List widget

(Added at v1.0)

The Layer List widget provides a list of operational layers and their symbols, and allows you to turn individual layers on and off. Each layer in the list has a check box that allows you to control its visibility. Some layers contain sublayers or subtypes.

The order in which layers appear in this widget corresponds to the layer order in the map. This widget allows you to change the order of layers in the map.

Configure the Layer List widget

This widget can be set to open automatically when an app starts. Hover over the widget and click the Do not open this widget when the app starts button to change the setting to Open this widget automatically when the app starts. (For widgets that you need to add to the app first, you can turn on this option after configuring the widget.)

1. Hover over the widget and click the Configure this widget button to open the configuration window.

   Note:

   If you need to add the widget to the app first, click a widget placeholder on the Widget tab. In the Choose Widget window that opens, select the widget and click OK.

2. Optionally, click the Change widget icon button and replace the default icon with an image of your own.

   A File Explorer window appears, allowing you to select a local image file to use as the widget icon.

3. Optionally, check the Show title check box to display the title label Layers on the widget panel.
4. Optionally, check the Show basemap check box to include basemap layers in the list.
5. Optionally, check the Show Legend check box.

   When this check box is checked, you can expand a layer to display its symbols.

6. Optionally, check the Expand all layers by default check box.

   This expands all group layers by default in your app, allowing them to be shown in the layers list.

7. Optionally, check the following options to appear on the layer context menu:
   • Zoom To
   • Transparency
   • Enable/Disable Pop-up
   • Move up/Move down
   • Open Attribute Table
   • Description/Show Item Details/Download
8. Uncheck layers in the map that you don't want to show on the list.
9. Click OK to close the window.
