在 R 中将条件面板与 PickerInput 结合使用

Using Conditional Panel with PickerInput in R

在下面给定的 R shiny 脚本中,我正在尝试使用带有 Picker Input shiny 小部件的条件面板。 pickerInput 中有三个选项,在选择 "times" 选项后,我希望使用条件面板创建新的 pickerInputs,使用 selectInput 可以实现以下内容,但我需要同样的选择器输入。谢谢,请帮忙。

library(shiny)
library(shinydashboard)
ui <- dashboardPage(
dashboardHeader(title = "Picket",titleWidth = 290),
dashboardSidebar(width = 0),
dashboardBody(
tabsetPanel(type = "tab",
            tabPanel("Overview", value = 1,

                     box(
                       column(1, 
                              dropdown(
                                pickerInput(inputId = "resources", 
                                            label = "", 
                                            choices = c("cases", 
                                                        "activities", 
                                                        "times"), 
                                            choicesOpt = list(icon = c("fa fa-bars", 
                                                                       "fa fa-bars", 
                                                                       "fa fa-safari")), 
                                            options = list(`icon-base` = "")),
                                circle = FALSE, status = "primary", icon = icon("list", lib = "glyphicon"), width = "300px"
                              ),
                              conditionalPanel(
                                condition = "input.Position == 'times' ",
                                dropdown(
                                pickerInput(inputId = "Id072", 
                                            label = "Select/deselect all options", 
                                            choices = c("A","Check-out", "b","c","d","e","f")
                                            )))))),

id= "tabselected"

            )

            ))


server <- function(input, output) { 
}
shinyApp(ui, server)

这个condition = "input.Position == 'times' ", b condition = "input.resources == 'times' ",不应该吗?
