The Salesforce* Maps admin for the company has been tasked with creating layers for the...

According to the Salesforce Maps documentation1, to create a datalayer, the admin must first select either the Personal or Corporate folder in the Layers tab. The Personal folder is for saving data layers privately so only the admin can see them, while the Corporate folder is for sharing data layers with other maps users. After selecting a folder, the admin can hover over New and select Data Layer, then name the data layer and select the data source, filter, and style options. If the admin does not select a folder before attempting to create a layer, all of the options will be greyed out and unavailable. References:
