Hi All,

I'm kind of new on the API 4.3 and I've bean searching everywhere but cant find the answer.

 

What I basically want to do is that when that all of my sublayers are not visible as default. When the user clicks a sublayer for viewing I would like to get the ID of the sublayer the user clicked so that I can refresh the search widget son that the user can search on the visible sublayer.

 

i read that with the listitem you can grab it but i don't know how to invoque that parameter on click

 

Hope someone can help me.

 

Here is a snippet of how I'm loading the layerlist

layer = new MapImageLayer({
            url: URL
        });

var view = new MapView({
            map: map,
            container: "viewDiv",
            extent: extent
        });

var layerList = new LayerList({
            view: view
        });

view.ui.add(layerList, "top-right");
