Is there any widget/ tool available that will toggle the visibility of multiple layers? (switch on certain layers and switch off other at a same time)
Ultimately the widget will act as one click option to turned on or off a group of pre-configured layers. An equivalent of "historic aerials" options in this mapping application. http://goo.gl/KrU70O
The application and the toggle layer tools are Geocortex Essential workflows . The tools turns on the desired historic aerial image service along with the latest Aerials in a background while turning off all the other layers.
This toggle is independent of layer visibility checked in applications layer list.
