[Cartoweb-users] legend icons

[Oliver Christen]

Or you could make one layer from each of your existing class and group all 
these layers in a layerGroup.
To hide the checkbox, simply use define a metadata for these layers in the 
layers.ini :

layers.****.metadata.nocheckbox = true

and add a check in layers.tpl :

{if !$element.layerMeta.nocheckbox}
<input
{if $element.layerRendering == 'radio'}type="radio" 
name="layers_{$element.parentId}"
{else}type="checkbox" name="layers[]" {/if}
value="{$element.layerId}" id="in{$element.nodeId}"
  onclick="javascript:updateChecked('{$element.nodeId}');
    CartoWeb.trigger('Layers.LayerShowHide');" {if 
$element.layerChecked}checked="checked"{/if} />
{/if}

That way you can define the icon via the existing .icon property in the 
layers.ini and still be able to use vector symbol on the map.
