Using a View with components

Learn how to use a View with map components and Calcite components, to create an application with a header, thumbnail and web map. The key aspect here is to show how to use map components, and then access the created map in your script code.

In this tutorial, you will load and display a pre-configured web map stored in ArcGIS Online, and use Calcite Components to lay out your application with a header and logo at top, and the map below. The title and logo to display in the header will come from the web map item. You will also learn to display a loading indicator until the map is ready.

Run the app

In CodePen, run your code to display the map.

The app should display a map showing predominant educational attainment in New York, with a thumbnail and title at the top.
