mapPosition
AUTO
Can be TOP, RIGHT or AUTO. AUTO is the default, it chooses TOP when any nested objects are found and RIGHT otherwise.
string

Optional transformations for feature properties for HTML, see transformations.
object
v2.0
mapClientType
MAP_LIBRE
The map client library to use to display features in the HTML representation. The default is MapLibre GL (MAP_LIBRE). Cesium (CESIUM) can be used for displaying 3D features on a globe, if Features - glTF is enabled.
string
v2.0
style
DEFAULT
An optional style in the style repository to use for the map in the HTML representation of a feature or feature collection. The style should render all data. If set to DEFAULT, the defaultStyle configured in the HTML configuration is used. If the map client is MapLibre, the style must be available in the Mapbox format. If the style is set to NONE, a simple wireframe style will be used with OpenStreetMap as a basemap. If the map client is Cesium, the style must be available in the 3D Tiles format. If the style is set to NONE, the standard 3D Tiles styling is used.
string
v2.0
removeZoomLevelConstraints
false
If true, any minzoom or maxzoom members are removed from the GeoJSON layers. The value is ignored, if the map client is not MapLibre or style is NONE.
boolean
v2.0
geometryProperties
[]
This option works only for CesiumJS as map client. By default, the geometry identified in the provider as PRIMARY_GEOMETRY is used for representation on the map. This option allows multiple geometry properties to be specified in a list. The first geometry property set for a feature will be used.
array
v2.0
maximumPageSize
null
This option can be used to set a custom maximum value for the limit parameter for the HTML output. If no value is specified, the value from the Features Core module applies. When using CesiumJS as a map client, a value of 100 is recommended.
number
v2.0
propertyTooltips
true
If true, on the single item page any property that has a description in the provider schema will get an info icon with the description as a tooltip.
boolean
v2.0
propertyTooltipsOnItems
false
If true, on the items page any property that has a description in the provider schema will get an info icon with the description in a tooltip.
boolean
v2.0
