What is the simplest way to use a checkbox input to toggle the visibility of a featureLayer?

Thanks Tim,

The example you gave me was very helpful and gave me the answers I've been looking for.

The sample provided shows the layers on the map in the legend. Is this legend dynamic where is will only show the symbology of layers in the map's extent (e.g. If a layer has 100 symbology classes, but only 5 appear in the map's extent, does the legend for that layer shrink to 5 swatches)?

Michael,

The legend will only show the layers of toggled feature. Meaning, all checked layers will show in your legend, doesn't matter if they are in your extend or not.

This example, along with the rest of the examples I can find, only show how to toggle dynamic layers. Does anyone know of an example on how to create a simple checkbox toggle for FeatureLayers? Need to use FeatureLayers for the popup templates?

Greg,

this works with every type of layer. Shouldn't make a difference if you use feature layers.

Hi Tim,

Are you saying I can load the "esri/layers/FeatureLayer" module and switch "ArcGISDynamicMapServiceLayer" to "FeatureLayer" when defining the variables for the service? I'm not having luck doing that.

Wait wait wait, I got it to work. You still have to reference a specific layer in the service url, as always.
Thanks Tim!!
