Add graphicsLayer to legend widget

Greetings, I'd like to be able to add graphicsLayers into my legend instance. Has anyone added a graphicsLayer to the legend widget?

Thanks, Tyler

Tyler,

The Legend dijit has a layerInfo property for manually specifying layers but it has this:

<Layer> layer Required A layer to add to the legend. Valid layer types are: ArcGISTiledMapServiceLayer,ArcGISDynamicMapServiceLayer.

I saw that graphicsLayer is not a valid type. I'm wondering if there is a way to hack into the legend's DOM get the graphics layer's symbology and dynamically create some HTML to push into the legend wrapper. Has anyone doen anything like that?

Tyler,

I have never had the need to do that but you can basically do anything using DOM manipulation. You would juts dojo query for the #legendDiv and add you new dom element to that.
