# General This section presents the layer's general settings.


1	Visible: Determines whether the layer is visible or invisible. Only visible layers are displayed on the map. Selectable: Determines if layer elements are selectable. If this option is not selected, the elements of the layer cannot be selected using the selection tools. Overview: Adds layer to application overview. Overview can be enabled by selecting View->Map overview or by using the CTRL-O keyboard shortcut.
2	Visibility thresholds define the scale range within which a layer is displayed on the map. If the displayed map scale does not fall within the minimum and maximum values, the layer will not be displayed. If the options are not selected, thresholds will be ignored. If a layer is grayed out in the layer manager, this indicates that it is not displayed due to visibility thresholds. Depending on what the JMap administrator has decided, it is possible that these options cannot be modified.
3	Attributes that are bound to the layer's elements are presented in this table. Attribute titles and types are indicated. Layer attributes are descriptive data associated with layer elements. They are used for mouseover bubbles, labels, thematic maps, etc.
