So basically I guess you're looking for this. But you have to check the Search widget in API 3.32 on you own because I have as well never worked with it. Here is the link to the 3.32 Search Class: Search | API Reference | ArcGIS API for JavaScript 3.32 <!DOCTYPE html>

In your code you are using ArcGIS API 3.32 and you can't require modules from the API 4.* like "esri/widgets/Search". Furthermore the order in the require statement and the function following have to match. require([
"esri/map",
"esri/dijit/Search",
"esri/graphic",
"esri/symbols/SimpleMarkerSymbol",
"esri/tasks/GeometryService",
"esri/tasks/ProjectParameters",
"esri/SpatialReference",
"esri/InfoTemplate",
"dojo/dom",
"dojo/on",
"dojo/domReady!",
], function (
Map,
Search,
Graphic,
SimpleMarkerSymbol,
GeometryService,
ProjectParameters,
SpatialReference,
InfoTemplate,
dom,
on
) {
//api code
});

I'd suggest as the LayerList widget is in fact a <ul> Element to change the CSS of the affected classes. <div class="row">
<div class="column">
<img src="first.jpg" style="width:100%">
</div>
<div class="second.jpg" style="width:100%">
</div>
</div>
<div class="row">
<div class="column">
<img src="third.jpg" style="width:100%">
</div>
<div class="column">
<img src="fourth.jpg" style="width:100%">
</div>
</div> .row {
display: flex;
}
.column {
flex: 50%;
padding: 5px;
} you can use "Flexbox CSS" (above) or "Floating CSS" (below). I'd go with Flexbox /* define width of column container */
.column {
float: left;
width: 50%;
padding: 5px;
}
/* Clear floats after image containers with after pseudoclass */
.row::after {
content: "";
clear: both;
display: table;
} Finally substitute the classes row and column with the classes used by esri, look for them by inspecting the element in the browser dev tools => layerlistul.png

How about if you try to calculate a median or average z value of all the features you have (if there are multiple ones) and then add this z value to the popup properties. Or if you have just this one single feature simply use the z value of the popup. (not very clean but it should prevent doing weird stuff). <!DOCTYPE html>

As far as I know these there are no more than the ones you listed. It only depends on the renderer which ones are available and which are not. For example with uniqueValueRenderer there is only count available and the type gives you the most common type of the features which are clustered together. See Styles and Configuration: FeatureReductionCluster | ArcGIS API for JavaScript 4.15

Hey guys I'm using JS API 4.15 and have some issues with the clustering / featureReduction. I am clustering a feature layer with an attribute called status. Right now every feature of the feature layer is clustered if it's inside the featureRadius. What I want to achieve is that if two features of the same layer are next to each other, but don't have the same status, that they don't get clustered together. Example: 5 features are within the clusterRadius, but only 3 of them also have the same status -> only those 3 should be clustered together and the other two ones stay as they are (if those remaining two features would have the same status obviously they'd get clustered together as well). https://developers.arcgis.com/javascript/latest/sample-code/featurereduction-cluster-filter/live/index.html In this sample we can see the same behaviour for example in the South the features are clustered together as "Hindu" although if we zoom in further, we can see that there were "Christian" features in the "Hindu" cluster. In my example this would mean that only the same religion (e.g."Hindu" features) gets clustered together. I am also using a uniqueValueRenderer for my feature layer as they do in the sample above. If anybody could provide a suggestion or sample code I'd be grateful! Thanks in advance and happy coding

for development purposes I like to declare the var view; outside of the require statements so I can get and set the view's properties in the browsers developer tools. Maybe this can help you out. For your particular case I'd do: view.scale = 3000 in the dev tools of the browser and see if it fits my needs.
