I need to filter features by one specific attribute which is same for every layer that I am using. I tried this tutorial https://developers.arcgis.com/javascript/latest/sample-code/featurefilter-attributes/ which workrs fine but just for one layer. How can I modify this code to add another layers? I want to filter on client side. My code is the same as in tutorial
You will need to apply the filter to each layer view, there is no general filter on the map.
I should not be much effort though, just iterate over the layers on the map, an in case of FeatureLayer apply filter to the FeatureLayerView.
