You can provide startup options to the JMap NG Core library or the JMap NG App.
Those options let you customize the behaviour of JMap NG at startup.
You can pass those options as URL parameters:
https://jmapdoc.jmaponline.net/services/ng/?ngProjectId=57ec1ca5-ddb8-4c71-ace4-0571129b017c
Or pass them as a JS object, through a globally scoped JS variable named JMAP_OPTIONS, like this:
All options are available as JS parameters, and some are also available as URL parameters. All URL query parameters are prefixed with "ng", to avoid naming collisions with eventual third-party query parameters (especially true if JMap NG is embeded in a div for instance).
The following tables present the list of JMap NG Core library's startup options:
Map options are gathered in a "map" json object in the javascript configuration.
The following table presents the list of JMap NG App's startup options:
