Highlight point features

This sample shows how to highlight point features in a layer. To highlight a feature, call the highlight method of the feature's corresponding layerView with the feature or its objectID as parameter. When passing features as parameters, they need to have an objectID. You can also pass the name of a pre-configured or custom HighlightOptions you want to use. Otherwise the default will be used.

view.whenLayerView(layer).then((layerView) => {
  // if a feature is already highlighted, then remove the highlight
  if (highlightSelect) {
    highlightSelect.remove();
  }

  // set the highlight on the first feature returned by the query
  highlightSelect = layerView.highlight(feature);
});
