r shiny

pickerInput从vector中选择所有值,r,dplyr,shiny,shinywidgets,R,Dplyr,Shiny,Shinywidgets,我有这样的pickerInput（来自shinyWidgets）： pickerInput("cities", "Choose a city", choices = list("Europe" = c("Warsaw", "Berlin", "Kyiv"), "Asia" = c("Tokyo", "Seoul&q

我有这样的
pickerInput
（来自
shinyWidgets
）：

pickerInput("cities", "Choose a city",
  choices = list("Europe" = c("Warsaw", "Berlin", "Kyiv"), 
    "Asia" = c("Tokyo", "Seoul")), 
  options = list(`actions-box` = TRUE),
  multiple = T)
我的计划是：按下“欧洲”键，我想要的是价值观​​“华沙”、“柏林”、“基辅”待选择。

这不是
shinyWidgets:：pickerInput的功能。请参阅此GitHub问题：
