Sample to get the list of available layers on servers and show checkbox list

Question

I want to get list of layers (like roads/ports etc) from ArcGIS server and show them using a checkbox list on the map. I was unable to find samples on how to retrieve the available layers list. Any examples demonstrating this would be of much help...

Hi Ken Buja,

Sorry for the late reply. yes, I want to show the layers list in an accordion on the map itself. Any sample would be of great help!

Thanks,

Are you trying to do something like this with an accordian panel?

Hey Ken,

Thanks for the great reply! It saved me a lot of time.

I'm now stuck and looking for the following features.

1. I want the layers checkbox to be visible but don't want to show them by default on page load. I tried doing the following, but this resulted in not showing the checkbox at all 😞
    map.on("layers-add-result", function (evt) {
        $.each(evt.layers[0], function (i, layer) {
            $.each(layer.layerInfos, function (index, info) {
                info.defaultVisibility = false;
            });
        });
        buildLayerList(evt);
    });

2. I want to show the checkboxes in a accordion like control inside the map area itself. To start with I placed the checkbox div inside the map div, but that resulted in blocking up the entire horizontal space for that much height. I tried with fixed width and relative/absolute placement... none worked.

Any hint/example would be of great help and would be much appreciated.

Thanks,
Biranchi
