Use folders to organize layers

Layers in a map can be organized into folders that hold similar or dissimilar layers. Map viewers can display the layers inside a folder as separate entities or as one unit, depending on whether you lock the layers together in the folder.

When you add layers to a folder, the folder appears on the Map details page in the list of layers. Two settings determine the way that map viewers interact with the folder's contents.

Folder visibility is represented by an open eye or closed eye. Visible? indicates whether the folder's layers and subfolders are visible on the map by default.

An open eye means that all layers and subfolders are visible by default. A closed eye means that none are visible by default. A dash means that there's a mixture of settings in the folder.
Locked state is represented by a padlock. Locked? indicates whether a map viewer can display or hide layers in this folder and its subfolders as separate entities.

A lock image means that the layers are always treated as a single entity. A crossed lock means that a map viewer can display or hide layers independently.

Once you've created folders in a map, you can click the tree symbol at the top of the layer list to display the complete contents of the map, including the folder hierarchy and the contents of all folders and subfolders.

The image hierarchy is represented as a tree form.

See Supported data formats and limits for limits on folders in a layer. There are no limitations on the following:

  • the number of layers in a folder
  • the size of a folder
  • the number of folders to which a layer can be added

However, although you can put an unlimited number of layers into a folder, only 15 vector layers can be displayed on a map at any one time. Therefore, locking a folder that contains more than 15 layers makes the viewing client unable to display the contents, even if the folder is set to Visible.
