Show all selectizegroupUI options but grey out?

Question

Is it possible to show all selectizegroupUI options but grey out the unavailable selections based off of what it already selected?

For example, when selecting a Manufacturer, show all other options but grey out if unavailable (and vice versa).

Could one combined the solution below with selectizegroupUI?

On a related note, select_group_ui doesn't seem to work/acknowledge NAs if the column name has a space in it - is it possible to overcome this?

mpg <- mpg %>%
   mutate(model = if_else(drv == "f" | drv == "r", NA, model)) %>% 
  rename("Model with space" = "model")
