Feature Layer zIndex

AndrewMurdoch1

Good Day

I'm trying to figure out how change the elevation / zIndex of layer at creation, assuming I have N layers, and I want 'Base' to be on the bottom, how do I go about that?  This is my layer creation code:

let offset = '';
  if (!data[0].attributes.geoLayerName.toUpperCase().includes('BASE')) {
    offset = 'Geometry($feature).z + 10000';
  } else {
    offset = 'Geometry($feature).z + 10';
  }

return {
  source: data,
  renderer: this.buildRenderSettings(colour, geometryType === 'point'),
  fields: this._fields,
  objectIdField: 'ObjectID',
  geometryType: geometryType,
  elevationInfo: {
    mode: 'absolute-height',
    featureExpressionInfo: {
      expression: offset
    },
    unit: 'meters'
  },
  spatialReference: {
    wkid: 4326
  }
};

I'm utilizing a 2D map.

Thanks

Thanks for the reply, it seems they made a large oversight.  I ended up reordering the map data before I convert it to Feature Layers which solves the problem.
