Expressions

Filter and paint configuration in style layers support Mapbox expression. Read more about expressions here.

WWT has implemented a expression superset which can be used together with Mapbox expressions.

Superset functions

isInQuery

["isInQuery"]:boolean

Returns true if the feature is included in the searched features, otherwise false.

isInMultiSelect

["isInMultiSelect"]:boolean

Returns true if the feature is selected using multi-select, otherwise false.

isActiveFeature

["isActiveFeature"]:boolean

Simplified version of activePoint.

Returns true if a feature from the same sourceId and sourceLayer has been click by the user. Will not work as expected, if more than one style layer on the same source is set to interactive.
