Hello @MichelMorgan , To disable scale, rotation and move, try by adding below properties "defaultUpdateOptions": { "enableRotation": false, "enableScaling": false, "enableZ": false, "multipleSelectionEnabled": false, "toggleToolOnClick": false } And add below event sketchView.on("update", function (event) { const eventInfo = event.toolEventInfo; if (eventInfo && eventInfo.type.includes("move")) { sketchView.cancel(); } });

Hello Team, We are using Arcgis JavaScript API 4.23 sketch and layer list widget. The issue is when any geometry is selected from sketch widget, LayerList widget additional button (custom) like to delete and cluster is hidden. We need to reopen the Layer list widgets to view the button's. Could you help us why LayerList widget is impacted when we use/select sketch widget geometry to draw? Is there any way to stop that behavior other than re-open LayerList widget? Enclosed html page sample is created in the ArcGIS JavaScript sandbox. Steps to reproduce issue:- 1. Expand Legend and click group 1. 2. Expand TOC (right side) and expand predefined group layer 3. click on sketch widget(in bottom) point geometry. 4. observe layerlist widget cluster, del icon gone <html>

Hello Team, cc: @Noah-Sager After analysis above issue we are able to find the root cause. When we remove any layer from the group after that label are not visible for all layers. We tried to loadAll group layers still issue is there. When we hide the feature layer from group and layerList then everything is working fine. Can anyone help me to why labels are not visible when we remove one layer from the group layer. We created one POC on the same issue: Steps 1. From Expand Legend( left side) click Group 1 and then click Group 2 once. 2. Now expand TOC(right side) and expand predefined group layer and click on del button(red background) for layer 'Accidental Deaths'. 3. Now re-open TOC and click on cluster button for all layers. You will observe labels are not visible on cluster points. Sample URL : Cluster

Sorry for late reply @Noah-Sager , We tried to create Sample using ArcGIS sample server layers and there it is non-reproducing. It is happening only with our app in Angular 9, where we create a feature layer from feature collection and toggle cluster for individual layers.

Hello Team, Using ArcGIS API 4.19 In our project we have one parent group layer and inside that multiple group layer which have collection of feature layers created from client side features. For each individual feature layer we can turn ON/OFF cluster. Example: 'Predefined' a parent group layer and added a child group layer 'Test' which have multiple feature layers like Test1, Test2, Test3, Test4. Suppose we turn ON cluster for 'Test1' feature layer. Everything works as expected. Now we added a new child group layer in Predeined group i.e. 'Custom' group layer which have multiple feature layers like custom1, custom2, custom3. When we turn ON cluster for 'custom1' layer, cluster is created, however it does not show labels on it. Same behavior for all 'Custom' group feature layers. Question:- Why cluster labels are not visible for 'Custom' group feature layers? Is this something default behaviour or some settings are required Cluster creation code:-

Hello Team, ArcGIS javascript API 4.22 we are using. In project we create custom content of popup template for each feature layer. When we turned on Cluster, cluster popup template is opened and on click of browse feature, we can browse individual features. The issue is when we try to browse individual feature, the field value is undefined except object id. Question- How to show feature's value in place of undefined Attaching sample code - For layers1 we created custom popup content. <html>

Thank you @UndralBatsukh for responding. Requirement is when a cluster is ON and on the map some feature is single, some are not. When single feature on the map, then it shows layer original symbol, i.e. picture marker and club features shown as cluster simple circle with labels. So at same time both picture and simple marker symbols will present on map for same layer.

Hello Team, I have a simple picture marker symbol feature layer. Requirement - When we turn ON cluster for that layer if single feature, then it should display layer original picture marker symbol and if more than 2 features, then it should display cluster symbol (simple marker symbol) with labels. When we turn OFF cluster, then layer will display as its initial state i.e. only picture marker symbols
