[null,null,["Last updated 2025-07-08 UTC."],[],["`ui.data.ActiveList` is an array-like container that, when updated, triggers updates in its associated UI component. It can be initialized with a list. Actions like adding to the `ActiveList` directly reflect in the UI. For instance, `Map.layers().add(myLayer)` adds a layer to the map. The constructor `ui.data.ActiveList(list)` creates an `ActiveList` object, and it allows the input parameter list, which is an optional list used to initialize the container.\n"]]
