I need to figure out how to set up check boxes to choose values to query from a data layer.  Some of the values will be a single category, such as 'Audiologist' or "Orthopedist'.  But there will also be a category that is more of a group "Mental Health", that might have subcategories of 'Alcohol',' Narcotics' If I could organize this using a checkbox tree, then the items that had subcategories could be grouped under a single item in the tree, which the ones that didn't would just be a one line with a checkbox.  I think this would give a cleaner look to the interface.  This is obviously exactly what's going on with the TOC, but I'm not dealing with layers. The Values will remain constant and I don't think I'll have even a dozen to deal with.  Once the user makes their selection, then I can use the values to create a where clause and then either a queryTask or a selectFeatures on featureLayer.  That results of the query will go into a grid.  What I'm envisioning isn't a TOC, or I'd just use that.  I'm having a hard time finding a good example of the checkbox tree.  I found this site, but it's enough out of date that the code isn't working for me. http://thejekels.com/cbtree/demos/ArcGIS.php   I vaguely remember a POI example on the ESRI site from a couple years back, but I can't find a working example of that either. If anyone has a better suggestion, I'd like to hear it.  ... View more

I have a clusterLayer based on the point clustering example:https://developers.arcgis.com/javascript/jssamples/layers_point_clustering.html  Toward the top, I define my infoTemplate and call the function to generate the clusters:       infoTemplateContent = "<b>Status: ${FlagStatusDescription}</b><br>"         +"Type: ${ItemFunctionDescription}<br>"         +"Agency: ${AgencyAcronym}<br>"+         "Address: ${EntityLocationAddress1}<br>"         +"City: ${EntityLocationCity}<br>"         + "IP address: ${II_IPAddress}";                                  infoTemplate = new InfoTemplate();         infoTemplate.setTitle("Server ID: ${Item_Name}");         infoTemplate.setContent(infoTemplateContent);                 createCluster(); Here's the function   function createCluster(){     var queryTask = new QueryTask(pathName+"/ArcGIS/rest/services/myService/MapServer/1");     var query = new Query();     query.returnGeometry = true;     query.where = '1=1';     query.outFields = ["*"];         queryTask.on("complete", function(results){         var inputInfo = {};         inputInfo.data = arrayUtils.map(results.featureSet.features, function(feature){           var point = feature.geometry;           var att = feature.attributes;           var pointX = feature.geometry.x;           var pointY = feature.geometry.y;             return {                 "x": pointX,                 "y": pointY,                 "attributes": att             };         });         var singleServerSymbol =  new SimpleMarkerSymbol(SimpleMarkerSymbol.STYLE_CIRCLE, 10,          new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([0,0,0]), 1),new Color([0,205,0,0.25]));         // cluster layer that uses OpenLayers style clustering           clusterLayer = new ClusterLayer({             "data": inputInfo.data,             "distance": 5,             "id": "clusterLayer",             "labelColor": "#fff",             "labelOffset": 10,             "resolution": res,             "singleColor": "#00ca00",             "singleSym": "singleServerSymbol",                       "singleTemplate": infoTemplate         });         var renderer = new ClassBreaksRenderer(singleServerSymbol, "clusterCount");             var single = new PictureMarkerSymbol("https://static.arcgis.com/images/Symbols/Shapes/GreenCircleLargeB.png", 18, 18);         var small = new PictureMarkerSymbol("https://static.arcgis.com/images/Symbols/Shapes/GreenPin1LargeB.png", 48, 48).setOffset(0, 15);         var medium = new PictureMarkerSymbol("https://static.arcgis.com/images/Symbols/Shapes/GreenPin1LargeB.png", 64, 64).setOffset(0, 15);         var large = new PictureMarkerSymbol("https://static.arcgis.com/images/Symbols/Shapes/GreenPin1LargeB.png", 96, 96).setOffset(0, 15);                 renderer.addBreak(0, 2, single);         renderer.addBreak(2, 25, small);         renderer.addBreak(25, 100, medium);         renderer.addBreak(100, 5001, large);          clusterLayer.setRenderer(renderer);         map.addLayer(clusterLayer, 1);         queryTask.on("error", function(err){             alert(err.details);         });        map.on("key-down", function(e){             if (e.keyCode == 27) {                 cleanUp();             }         });     });     queryTask.execute(query); }  function cleanUp() {     map.infoWindow.hide();     clusterLayer.clearSingles();   } I'm noticing that if I first click on a cluster to get information and follow that with the geocoder Widget, the infoContents that popup from my geocoder's showLocation function continues to retain the information from the clusterLayer.  It does start with evt.result.name,but also has the arrow indicating additional content.  When you click the arrow, you see the additional content content is the previously show information from the clusterLayer.    function showLocation(evt){        var symbol = new SimpleMarkerSymbol();        symbol.setStyle(SimpleMarkerSymbol.STYLE_CIRCLE);        symbol.setColor(new Color([255,128,0,0.75]));        map.graphics.clear();        var point = evt.result.feature.geometry;        var graphic = new Graphic(point, symbol);        map.graphics.add(graphic);        map.infoWindow.setContent(evt.result.name);        map.infoWindow.show(evt.result.feature.geometry);    }  It seems like the the cleanUp function for the clusterLayer would take care of this.  This project contains sensitive data, so I'm sorry I can't give you a link to the actual project. ...
