Enable feature selection on mapimagelayer

Question

I am pulling data from a MapServer, now I'd like to be able to interact with features on each of the layers to enable pop up of feature.

my very simple code has this so far:

const mapLayer = new MapImageLayer({
        url: e.url,
        opacity: 0.5,
      });

view?.map.add(mapLayer);

Any way to enable pop up template for each of the layers that come through? or have them automatically converted to featurelayer by default?

Hi there,

You need to set the popupTemplate on the sublayers as shown here: https://developers.arcgis.com/javascript/latest/api-reference/esri-layers-support-Sublayer.html#popupTemplate

That will work when you have the layer, however in my case I don't and it can be many or 1.

Eventually I solved it this way.

mapServerLayers.loadAll().then(() => mapServerLayers.allSublayers.forEach((e) => e.popupTemplate = e.createPopupTemplate({visibleFieldNames: viewFields})));
