Selection effect settingsSource:
Allows customization of the rendering of
selected graphic elements.
opts_selection for interactive geometries in panels,
opts_selection_key for interactive scales/guides and
opts_selection_theme for interactive theme elements.
opts_selection_inv for the effect on the rest of the geometries,
while some are selected (inverted operation).
opts_selection( css = NULL, type = c("multiple", "single", "none"), only_shiny = TRUE, selected = character(0) ) opts_selection_inv(css = NULL) opts_selection_key( css = NULL, type = c("single", "multiple", "none"), only_shiny = TRUE, selected = character(0) ) opts_selection_theme( css = NULL, type = c("single", "multiple", "none"), only_shiny = TRUE, selected = character(0) )
css to associate with elements when they are selected. It must be a scalar character. It can also be constructed with
girafe_css(), to give more control over the css for different element types.
selection mode ("single", "multiple", "none") when widget is in a Shiny application.
disable selections if not in a shiny context.
character vector, id to be selected when the graph will be initialized.

fill style with the
be aware that the browser's CSS engine will apply it also to line elements,
if there are any that use the selection feature. This will cause an undesired effect.
To overcome this, supply the argument
in order to set the
fill style only for the desired elements.
