Innovate’s Grouped Layerlist widget addresses a common issue faced within the geospatial community and by Esri WebApp Builder users; it enables customized groupings of layers. Users can quickly and easily view the specific information that they need to visualize. The Grouped Layerlist widget is a widget for utilization within Esri’s Web Application Builder. This widget provides a layerlist that can be organized by custom themes/groups (e.g. Transportation, Gas, Railroads, etc.). When the Grouped Layerlist widget is configured in the Web Application Builder, themes/groups can be created and layers within the web map associated with the application can be grouped into those themes. Each layer within a theme has options for changing the layer transparency, enable/disable popups, change layer symbology, view attribute table, and showing item details depending on the layer type.For example, if a user needed to see all the data relevant to railroads, the Developer could easily create a new group titled, “Railroad.” They would then select from the list of available layers in the map what layers are related to Railroads and save. Now, users could select the “Railroad” option in the Grouped Layerlist rather than manually selecting individual layers every time.
Over the past year Innovate has worked with World Wildlife Foundation (WWF) Norway to make this new widget a reality. Thanks to the generosity of the WWF, we have been allowed to make this widget available to the Web AppBuilder community. Below is a link to a short video to demonstrate how the widget works. We have also created a public GitHub repository, so others in the community can use the code at no cost!
