Hawaii, Alaska and other US territories to be displayed near contiguous US map

Question

Hello,

I am researching solutions for having Hawaii, Alaska and other US territories near the contiguous US map. The map is displayed within a web application.

I did find some solutions that allows them to be inserted in different data frames and then controlling the extent. https://developers.arcgis.com/javascript/latest/sample-code/views-composite-views/. However, when I zoom into a county in contiguous US map Hawaii, Alaska which are in separate frames are also there. Is it possible that when a user zooms into a county or any other region within a state the view removes Alaska, Hawaii and only shows zoomed area. This should also happen when we zoom into Hawaii and Alaska too.

Actually, a better way would be to use the FeatureFilter on each layer view. Using the example above, I filtered the main view to not show Alaska and Hawaii (lines 158-162) and make it zoomable to show the filtered states (line 146). This maintains the interactivity when mousing over the counties using only the one FeatureLayer. Create an app with composite views | Sample | ArcGIS Maps SDK for JavaScript 4.27

Instead of using a single FeatureLayer containing the map that is added to all of the data frames, why not use different FeatureLayer for each data frame, each with its own definitionExpression? This way you can filter out the states you want to either exclude or include for that specific data frame.
