When you have a lot of points and only want to show one popup at a time, the best approach is to create one popup and reuse | |
it rather than creating a popup for each point feature. By doing this the number of DOM elements created by the application is greatly | |
reduced which can provide better performance. This sample creates 3 point features. If you click on any | |
of them, a popup will be displayed with the content for that point feature. | |
