Looking for any examples of a collapsible layer list that Auto fills with my layers.
I have seen some really basic layer list examples on the api page but nothing that allows collapsible areas and auto filling of your layers.
I am trying to create 3 different areas as seen below. Were the box next to the ------------- would collapse that section.
But I want it to auto fill the layers from my .js page.
Right now I am adding layers to the list and adding check boxes BUT THERE it is not collapsible
legendLayers.push({ layer: FloodZonelayer, title: 'Flood Zones' });
// ADD CHECK BOXES FOR LAYERS
map.on('layers-add-result', function () {
//add check boxes
arrayUtils.forEach(legendLayers, function (layer) {
var layerName = layer.title;
var checkBox = new CheckBox({
name: "checkBox" + layer.layer.id,
value: layer.layer.id,
checked: layer.layer.visible
});
checkBox.on("change", function () {
var targetLayer = map.getLayer(this.value);
targetLayer.setVisibility(!targetLayer.visible);
this.checked = targetLayer.visible;
});
//add the check box and label to the toc
domConstruct.place(checkBox.domNode, dom.byId("toggle"), "after");
var checkLabel = domConstruct.create('label', {
'for': checkBox.name,
innerHTML: layerName
}, checkBox.domNode, "after");
domConstruct.place("<br />", checkLabel, "after");
});
});
//ADD THE LEGEND AND XY COORDINATES
map.on("layers-add-result", function (evt) {
// CYCLE through and grab all the layer names to add to the LEGEND PLUS
// Remove layers not inteneted for the legend.
var layerInfo = arrayUtils.map(evt.layers, function (layer, index) {
if (layer.layer.id === "PastLocations" || layer.layer.id === "District" || layer.layer.id === "weatherlayer") { return { }; } //Hides Layers in the Legend
else { return { layer: layer.layer, title: layer.layer.name }; } //Else return All others
});
// CYCLE through and grab all the layer names to add to the LEGEND
if (layerInfo.length > 0) {
var legendDijit = new Legend({
map: map,
layerInfos: layerInfo,
}, "legend");
legendDijit.startup();
legendDijit.refresh();
}
});

I know this is not the way to do this although I don know of any other way to accomplish what I am looking for...
This is how I put on a large band-aid
- I still have to clean up the CSS to hide the clumsiness of this approach...especially with nesting the accordion panes..
- I still have to clean up my code so don't be too judgmental I repeated the code to build the legend layers in each of the accordion panes.
- I can put if then statements in this section to decrease the amount of code - map.on('layers-add-result', function () {
This gives you something like this in your panel... I have a container for Weather, Incidents, Other Layers.
If I do a little CSS work I can get ride of the frames and color backgrounds and make this look a little more appealing.
The example below does not have all the layers in the image. In my below example it would simply put one feature layer in each of the 3 accordions
Follow the "legendLayers1.push" below from each FeatureLayer to the function below it.
legendLayers1.push({ layer: WeatherImpactWashout, title: 'WeatherImpact Washout' });
legendLayers2.push({ layer: WeatherImpactWashout, title: 'WeatherImpact Washout' });
legendLayers2.push({ layer: WeatherImpactWashout, title: 'WeatherImpact Washout' });
