Something like this? https://developers.arcgis.com/javascript/latest/sample-code/sandbox/?sample=layers-scenelayer-feature-masking Scene and feature layers co-exist.

As a user you cannot upload custom widget to a running application. As a developer you can create your own application where you load your webmap and as many custom widgets you wish. You can use Experience Builder, developer's version, Experience Builder on Enterprise Portal v. 11 or higher or simply use Calcite + ArcGIS Javascript API. Stay away from Web AppBuilder since it will be phased out soon.

During the 2023 Dev Summit this app was shown to demo by @KellyHutchins and @MNIT-Kitty-Hurley the ability to create accessibility maps with JS and Calcite. https://codepen.io/kellyhutchins/pen/QWVvGZq?editors=1010 In this app, a click on the map, shows the record on the table. My question is if you click a graphic, how the table can scroll to that selected feature if there are hundreds of features. Also, how can we add a vertical scroll to the table. Thank you.

Thank you. Yes, it does work if you place the notices inside another div , but it doesn't answer my question: "The Calcite-panel doesn't allow horizontal elements?" I used the panel in other scenarios, for example, where I placed a tab inside the panel. Several elements inside the tab were aligned horizontally with no issues. So, I guess the answer to my question is No unless if you use another component inside the panel and be the parent of the elements to be aligned horizontally.

I have two calcite-notice elements that I'd to display side by side (horizontally). Both calcite-notices to be posted inside a calcite-panel. The issue is that the notices are displayed vertically. If I remove the calcite-panel tag, then the calcite-notices appear as intended, side by side. The Calcite-panel doesn't allow horizontal elements? https://codepen.io/lkoumis1/pen/KKGXNqv?editors=1000 @KittyHurley?

It is kind of odd that there is no calcite icon for accessibility. The person-2 comes close but it is not the universally accepted icon for accessibility. The person-2 icon can be viewed at: https://developers.arcgis.com/calcite-design-system/icons/?icon=person-2&library=Calcite%20UI&query=person-2 The universally accepted icon for accessibility is

Hello @MNIT-Kitty-Hurley @KellyHutchins I turned on the Windows 11 narrator and I access the site at: https://kellyhutchins.github.io/DevSummit2023-A11y/demos/MapDescription.html but all I hear is the chrome version and that the zoom tool is present and not the map desciption which is "The map summarizes the count, and rates, of accidental deaths in each state." Am I messing something or it is not working with the win 11 narrator? Thank you.

@WilsonIonara There is nothing to install. Just update the links to the calcite components to version 1.0.4 or later. <script type="module" src="https://js.arcgis.com/calcite-components/1.0.4/calcite.esm.js"></script>
<link rel="stylesheet" type="text/css" href="https://js.arcgis.com/calcite-components/1.0.4/calcite.css" />

Without seeing your code, I don't know what you already have. Is your import like this? import "@esri/calcite-components/dist/components/calcite-button";
import "@esri/calcite-components/dist/calcite/calcite.css"; and your file structure like this:

I have this simple query and want to display the results to a feature table. However, the table never appears. I believe the root of the issue is the async. So, I tried using promises to no avail. I verified that the query works and I can see results on the map and the label about the number of features found. getQuery = async (SQLwhere) => {
let thelayer = this.state.LayerObject;
let query = thelayer.createQuery();
query.where = SQLwhere;
let thevalues = [];
query.outFields = ["*"];
query.returnDistinctValues = false;
query.returnGeometry = true;
thelayer
.queryFeatures(query)
.then((results) => {
numberofgraphics = results.features.length;
const featureTable = new FeatureTable({
view: this.state.jimuMapView.view,
layer: thelayer,
container: this.tableRef.current,
});
let graphics = results.features;
numberofgraphics = graphics.length; In html <div>
<Label
id="results"
size="sm"
style={{ fontSize: 14, fontWeight: "bold", color: "red" }}
>
There are {numberofgraphics} feature(s) found.
</Label>
<div
id="tableDiv"
style={{
marginTop: "10px",
marginLeft: "10px",
width: "440px",
height: "300px",
}}
ref={this.tableRef}
/>
</div>
