# Creating a menu for displaying groups of objects
Open in CodeSandbox
YMapsML is a language for describing geographical objects.
In YMapsML, each geographical object is associated with a geometric shape
and a geo object that is used for displaying this shape on the map. The shape definitions and their anchors to geographical coordinates are set in
corresponding YMapsML elements. The gml:Point element is designated for the "point" shape.
The visual appearance of displayed objects is set in the
repr:Representation element.
For detailed instructions on setting styles for displayed objects,
see the documentation.
Use the geoXml.load function for loading YMapsML data. After data is loaded, the function converts it to
GeoObjectCollection and passes it to the handler function as a parameter.
