The basic web template from ArcGIS.com has a setting in the index.html to turn on/off the layerlist ( displaylayerlist: true,)
By default is on. However the map shows only the legend. In the layout.js , if the displaylayerlist: true then it should:
//Create a menu with a list of operational layers. Each menu item contains a check box
//that allows users to toggle layer visibility.
according to the comments posted in the file.
However it does not.
Is it a bug?
Thank you.
