Add a layer list — add_layer

Lists the map's layers, with a checkbox each. Every layer add_layer() drew appears under the name it was given.

Usage

add_layer_list(
  map,
  position = NULL,
  expand = FALSE,
  show_filter = NULL,
  filter_placeholder = NULL,
  drag_enabled = NULL,
  selection_mode = NULL,
  ...
)

Arguments

map: Defines which map or arc_map_proxy() to modify.
position: default NULL. Defines which corner it sits in, one of "top-left", "top-right", "bottom-left", "bottom-right", or the direction-aware "top-start", "top-end", "bottom-start", "bottom-end". Each widget has its own default.
expand: default FALSE. Defines whether the widget is collapsed behind a button rather than drawn open. Worth it for the panels - the legend, layer list, basemap gallery - which otherwise cover the map. Collapsed widgets sharing a corner close each other when opened.
show_filter: default NULL. Defines whether a filter box is drawn above the list.
filter_placeholder: default NULL. Defines that box's placeholder text.
drag_enabled: default NULL. Defines whether layers can be reordered by dragging.
selection_mode: default NULL. Defines how items are selected, one of "none", "single", "multiple", or "single-persist".
...: Named properties of the component itself, written either snake_case or camelCase. map_widgets() lists what each one takes.

Value

map, with the widget added.
