Selection Symbols in the 3.x JavaScript API

Good Morning,

Is there a way to force selections on feature layers to use the standard renderer instead of a different selection symbol? I just want the selected features to display as usual with no modification.

Thanks,

Nathan

Hi @NathanHeickLACSD, how are you selecting the features? Is this from a query or via a popup?

You might be able to use the getSelectedFeatures and getSelectedFeatures methods to override the highlight:

Or make it 100% transparent in the popup:

Hi Noah,

This is for some custom widgets. I want to select features in a layer. This layer has scale dependencies. I want to highlight the selected features at all scales using a separate graphics layer. At the scales where the layer is visible, I want the selected features in the layer to display normally. I still want the layer to have and store the selection. However, I don't want the layer being selected to change its display at all.

Also, are you implying that the features returned from getSelectedFeatures can be mutated and the map will update?
