Composite (item)
Note
This page is automatically generated from the source code, and is a bit rough. If you have trouble, check the source code for this type or post a message to the forum.
A CatalogItem composed of multiple other catalog items. When this item is enabled or shown, the composed items are enabled or shown as well. Other properties, including CatalogItem's rectangle, CatalogItem's clock, and CatalogItem's legendUrls, are not composed in any way, so you should manually set those properties on this object as appropriate.
Initialization File properties:
"type": "composite"

zoomOnEnable
A value indicating whether the map will automatically zoom to this catalog item when it is enabled.
Note that within a single init source:
- Catalog items with both
isEnabledandzoomOnEnableset to true will override the top-levelinitialCameraproperty. - If multiple catalog items have both
isEnabledandzoomOnEnableset to true, it is undefined which one will affect the camera.
In the case of multiple init sources, however, the camera will reflect whatever happens in the last init source, whether
it is a result of a zoomOnEnable or an initialCamera,
