hi i am trying to show markers above webmap combined with a layer of nz boundaries, my markers hide behind this layer, when i use this webmap.

i have used gray basemap with a layer added on it in arcgis online webmap.

then i called this webmap.

i don't know how to show these markers above this webmap.

This is my code below

                function(watchUtils,MapView, WebMap,Graphic,domConstruct,Popup,Point,FeatureLayer, IdentityManager,  GraphicsLayer, webMercatorUtils) {   
                    webmap = WebMap.fromJSON(<?=$basemap_string1 ?>);

                /////Start view part
                var view = new MapView({
                  map: webmap,
                  container: "booking_map",

Hi,

thy to add your graphics layer and ser its index to 0.

https://developers.arcgis.com/javascript/latest/api-reference/esri-WebMap.html#addMany

 

webmap.addMany([ graphicsLayer], 0); 

Does it help?

BR,

Adam

No sorry @nita14 it doesn't work, the markers load first and then the layer load on it, and hide. the markers

Hi,

Just try to do not use webmap. Construct the layers manually by url and add them to the map.

Just like in this example:

https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=layers-feature...

BR,

Adam
