Add a basemap gallery — add_basemap

Lets the reader swap the basemap for any in the gallery. add_basemap_ toggle() is the two-basemap version, a single button.

Usage

add_basemap_gallery(map, position = NULL, expand = FALSE, disabled = NULL, ...)

add_basemap_toggle(
  map,
  position = NULL,
  expand = FALSE,
  next_basemap = NULL,
  show_title = 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.
disabled: default NULL. Defines whether the gallery is greyed out.
...: Named properties of the component itself, written either snake_case or camelCase. map_widgets() lists what each one takes.
next_basemap: default NULL. Defines the basemap to toggle to, as an id from Basemaps.
show_title: default NULL. Defines whether the basemap's name is drawn under the button.

Value

map, with the widget added.

Examples
