To improve load performance, Mango doesn't let all layers in the legend be turned on and off as you would in a desktop GIS program.

If you have a layer or a group of layers that you would like the end user to be able to turn on or off you will need to put them in a layer group.

How To Use

Just click on the checkbox next to the layer in the legend to turn it on or off.

How To Configure

See the following section in the documentation for more details.
