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

[BiranchiPanda]

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, While the above example is helpful is toggling the layers list, I'm looking for he following things as well:
1. Getting list of available layers on server
2. Showing them on an accordion like control on the maps whose visibility can be toggled.

Thanks for your answer!

Take a look at this example that shows how checkboxes for all visible layers are added from multiple services.

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

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

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!
