Layer order in a legend

Question

Hi,

There is no order by geometry type in a legend created with a legend widget.

How  layers can be ordered? Generally, we need to implement the rule:

- points

- lines

- polygons

bottom - polygons.

Any help will be appreciated.

Thank you for response, Panagiotis Papadopoulos.

Unfortunately, we have no geometry type when working with ArcGISDynamicMapServiceLayer.

So, how we obtain that geometryType?

this is a sample code

......
 //add the legend
 map.on("layers-add-result", function (evt) {
 var layerInfoLines = [];
 arrayUtils.map(evt.layers, function (layer, index) {
 if (layer.layer.geometryType === "esriGeometryPolyline"){
 layerInfoLines.push({layer:layer.layer, title:layer.layer.name});
 }
 });
 var layerInfoPolygons = [];
 arrayUtils.map(evt.layers, function (layer, index) {
 if (layer.layer.geometryType === "esriGeometryPolygon"){
 layerInfoPolygons.push({layer:layer.layer, title:layer.layer.name});
 }
 });
 var layerInfo = layerInfoPolygons.concat(layerInfoLines);

if (layerInfo.length > 0) {
 var legendDijit = new Legend({
 map: map,
 layerInfos: layerInfo
 }, "legendDiv");
 legendDijit.startup();
 }
 });

.....

and here see a live sample
