Learn how to display feature attributes in a pop-up .
A pop-up , also known as a "popup", is a visual element that displays information about a feature when it is clicked. You typically style and configure a pop-up using HTML and CSS for each layer in a map. Pop-ups can display attribute values, calculated values, or rich content such as images, charts, or videos.
In this tutorial, you create an interactive pop-up for the Trailheads feature layer in the Santa Monica Mountains. When a feature is clicked, a pop-up is displayed containing the name of the trail and the service that manages it.
You need a free ArcGIS developer account to access your dashboard and API keys . The API key must be scoped to access the services used in this tutorial.
To get started, either complete the Display a map tutorial or use this pen . To access ArcGIS location services , you need an API key .
Go to your dashboard to get an API key .
In CodePen , update apiKey to use your key.

In CodePen , run your code to display the map.
The map view should display the Trailheads feature layer . When you click a feature, the name of the trailhead and its park name is displayed in a pop-up.
